Question 1

1. Are lab grown diamonds real diamonds?

Accepted Answer

Yes. A lab grown diamond is carbon in the same cubic crystal structure as a mined diamond. Same hardness (10 on the Mohs scale), same refractive index, same thermal conductivity, same everything a gemologist can measure. The Federal Trade Commission dropped the word "natural" from its definition of a diamond back in 2018 for exactly this reason. The only real differences are origin and price. One grew underground over a very long time. The other grew in a machine over a few weeks. The stone doesn't know the difference and neither will anyone looking at your hand.

Question 2

2. Are lab grown colored diamonds real colored diamonds?

Accepted Answer

Yes, though the color usually arrives by a different route. In a natural pink diamond, the color comes from distortion in the crystal lattice caused by enormous pressure. In a lab grown pink, the color is almost always created after growth by irradiating a nitrogen-rich diamond and then heating it, which produces nitrogen-vacancy centers that absorb light in the green-yellow range and leave you with pink. Both are diamonds. Both are pink. One is a geological accident and one is a controlled process, and the controlled process is exactly why lab grown pinks can be pushed to saturation levels nature almost never produces at size. That's a feature for the factory and a problem for the person wearing it. Which is why, when we work in pink, we select Fancy Light. That's the intensity natural pinks actually occur in at wearable sizes, so it's the intensity that reads as a diamond instead of a decision made by a machine. The control that lets a lab overshoot is the same control that lets us stop exactly where we want to. Most of the industry uses it to go loud. We use it to get it right.

Question 3

3. Can a jeweler tell a lab grown diamond from a natural one?

Accepted Answer

Not by looking at it. Not with a loupe, not with a microscope, not with the little pen tester at the mall. Identification requires laboratory instruments that read growth patterns, fluorescence, and phosphorescence signatures. Both GIA and IGI screen every stone they grade. Anyone who claims they can eyeball the difference is telling you a story about themselves, not about the diamond. One enormous caveat, and it's the whole reason this company exists. That's true of the stone. It is not true of the situation. Walk into a room with a five carat Fancy Vivid pink on your finger and everyone who knows anything will know, instantly, because a natural stone at that color and that size would be an eight-figure object with a name and a Wikipedia page. Same for Fancy Intense, Fancy Deep, and Fancy Dark at size. The diamond passes. The math doesn't. Nobody can identify a lab grown diamond by looking at it. Plenty of people can identify a bad decision by looking at it. Not by looking at it. Not with a loupe, not with a microscope, not with the little pen tester at the mall. Identification requires laboratory instruments that read growth patterns, fluorescence, and phosphorescence signatures. Both GIA and IGI screen every stone they grade. Anyone who claims they can eyeball the difference is telling you a story about themselves, not about the diamond. One enormous caveat, and it's the whole reason this company exists. That's true of the stone. It is not true of the situation. Walk into a room with a five carat Fancy Vivid pink on your finger and everyone who knows anything will know, instantly, because a natural stone at that color and that size would be an eight-figure object with a name and a Wikipedia page. Same for Fancy Intense, Fancy Deep, and Fancy Dark at size. The diamond passes. The math doesn't. Nobody can identify a lab grown diamond by looking at it. Plenty of people can identify a bad decision by looking at it.

Question 4

4. How are lab grown diamonds actually made?

Accepted Answer

Two methods. HPHT (High Pressure High Temperature) recreates the underground conditions with a press, growing a diamond around a seed crystal in a molten metal flux. CVD (Chemical Vapor Deposition) uses a methane plasma in a vacuum chamber to deposit carbon onto a seed layer by layer. HPHT tends to dominate for fancy yellows, because the nitrogen that causes yellow is easy to introduce in that environment. CVD stones are frequently treated after growth with heat, pressure, irradiation, or some combination, which is how most of the pinks on the market get to be pink.

Question 5

5. Is a lab grown diamond the same as moissanite or cubic zirconia?

Accepted Answer

No, and it's worth being blunt about this because the internet muddles it constantly. Moissanite is silicon carbide. Different chemical composition, different material, and roughly 2.4 times the dispersion of diamond, which is why it throws that unmistakable rainbow disco flash that reads as costume jewelry to anyone paying attention. Cubic zirconia isn't in the conversation at all. A lab grown diamond is a diamond. Moissanite is a diamond simulant. The word people are looking for is "simulant" and the industry avoids it because "lab created moissanite" sounds so much closer to "lab created diamond" than it deserves to.

Question 6

6. Do lab grown diamonds come with certificates?

Accepted Answer

Yes. IGI grades the majority of lab grown stones. GIA issues reports for them too. A legitimate report will say "laboratory-grown" on its face, and it should disclose whether the color is as-grown or the result of post-growth treatment. That treatment disclosure is the line most retailers hope you skip. If a pink or blue lab grown stone is being sold with no mention of treatment anywhere, it isn't because there wasn't any. All Every Stone pieces ship with their IGI or GIA report, and I'll point you to that line myself.

Question 7

7. Will a lab grown diamond fade, cloud, or change color over time?

Accepted Answer

No. This one comes up constantly and it's a myth born from people confusing diamonds with moissanite (which doesn't fade either) and with cheap treated gemstones (some of which absolutely do). The color centers in a diamond are structural. They are part of the crystal. Barring a jeweler's torch or several thousand degrees of heat, they aren't going anywhere. What actually happens is your diamond gets covered in hand lotion and soap film and looks dull, and then you clean it and it looks new. That's the whole lifecycle.

Question 8

8. So why does most lab grown diamond jewelry look cheap?

Accepted Answer

Two reasons, and the second one is the one nobody says out loud. The first is that it's priced like a commodity and set like one. The industry decided lab grown was the discount aisle, and discount aisles get discount mountings. Stamped heads, thin shanks, a generic halo, and out the door. The stone got cheaper and nobody spent a dollar of the savings on design, which is a genuinely strange decision when you think about it for more than ten seconds. The second is color. Since a lab can dial saturation wherever it wants and Fancy Vivid is the grade that sells, almost everything on the market is Fancy Intense, Fancy Vivid, Fancy Deep, or Fancy Dark. Those are the grades that turn a diamond into a highlighter. A Fancy Deep or Fancy Dark stone reads as murky and closed off, and a Fancy Vivid at five carats reads as plastic, because your eye has spent your entire life learning what saturated color at that size means and it means costume. The producers aren't confused about this. Loud photographs better, loud sells online, and the thing arrives looking like a party favor. The technology made extraordinary stones available to people who could never have touched them before. The correct response was to build better jewelry around them. Every Stone exists because almost nobody did.

Question 9

9. What is a fancy color diamond?

Accepted Answer

A diamond whose color is saturated enough to fall off the standard D to Z colorless scale entirely. D to Z measures how little color a white diamond has, and Z is where the scale gives up. Anything with more color than that gets graded on a separate system built for color rather than the absence of it. Every hue exists in diamonds: yellow, brown, pink, blue, green, orange, purple, gray, red, and black. They occur in wildly different frequencies, which is where all the pricing drama comes from.

Question 10

10. What are the fancy color grades in order?

Accepted Answer

GIA's fancy color scale runs: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep, Fancy Dark. The thing nobody tells you is that this is not a quality ranking. It's a description of how much color is present. Fancy Vivid isn't a better diamond than Fancy Light any more than a shout is a better sentence than a normal speaking voice. It's a more expensive one in the natural market, which is why the entire lab grown industry chases it.

Question 11

11. Should I always buy the most saturated color I can afford?

Accepted Answer

No, and in lab grown specifically I'd argue the opposite. Vivid, Intense, and Deep are where the fakeness lives. When a lab grown stone is pushed to Fancy Vivid or Fancy Intense at four or five carats, you're wearing a color at a size that essentially does not occur in nature, and your eye clocks it even if your brain can't explain why. Fancy Deep and Fancy Dark have a separate problem: they're so heavily toned that the stone stops returning light and starts looking like a chip of hard candy. Fancy Light and Fancy read as real, because those are the intensities natural stones actually show up in at sizes you'd wear. That's not a compromise grade. That's the grade that's telling the truth. Buy the diamond that looks like a diamond, not the one that looks like a marketing decision.

Question 12

12. What causes color in a diamond?

Accepted Answer

Different mechanisms per color, which is why some are common and some barely exist. Nitrogen produces yellow. Boron produces blue. Pink and red come from distortion of the crystal lattice under pressure, with no impurity involved at all. Green comes from natural radiation exposure altering the structure. Brown comes from lattice distortion too, at a different scale. Black is usually heavy graphite or mineral inclusions rather than body color. This matters because impurity-driven colors are relatively easy for a lab to reproduce, and structure-driven colors are not. Nobody has figured out how to grow a convincing pink from scratch. They irradiate it afterward instead.

Question 13

13. Why do so many lab grown colored diamonds look fake?

Accepted Answer

Size and saturation mismatch, mostly. In nature, the strongest colors show up in the smallest stones. Across the entire history of Rio Tinto's Argyle tender, only ten stones ever exceeded three carats. When you put a Fancy Vivid pink on someone's hand at six carats for four figures, you have created something the world has essentially never seen, and it looks like it. The second reason is the setting. Color is relational. A pink diamond dropped into a plain white gold solitaire has nothing around it to argue for its color, so the color just sits there looking dyed. The result photographs beautifully and wears like a mistake, which tells you exactly who those stones were made for. They were made for the listing photo, not for you.

Question 14

14. What do hue, tone, and saturation mean?

Accepted Answer

Hue is the color itself (pink, blue, yellow). Tone is how light or dark it is. Saturation is how intense the color is. One useful detail: colored diamonds are graded face-up, in the position you'd actually wear them. Colorless diamonds are graded face-down against a white tray, because for those the entire point is finding color you don't want. Two opposite jobs, two opposite methods.

Question 15

15. Does clarity matter in a colored diamond?

Accepted Answer

Much less than you've been trained to think. In colorless diamonds, clarity is a headline number because there's nothing else to look at. In fancy colors, color leads and clarity follows. Plenty of famous natural pinks are heavily included, and in pink specifically the graining that comes with the color mechanism is part of why the stone is pink at all. Chasing VVS in a colored diamond is spending money in the one place your eye will never look.

Question 16

16. What does a secondary hue like "purplish pink" or "greenish yellow" mean?

Accepted Answer

The modifier is the secondary hue and the last word is the dominant one. Purplish pink is a pink diamond with purple in it. Greenish yellow is a yellow diamond leaning green. The trade often treats modifiers as a discount, and I think that's mostly laziness. My own engagement ring is a natural fancy greenish yellow, and I get asked about it everywhere I go, which never happened with any colorless stone I've owned. The modifier is frequently the interesting part.

Question 17

17. Are lab grown pink diamonds real pink diamonds?

Accepted Answer

They're real diamonds and they're really pink. Whether they're "real pink diamonds" in the sense the natural market means depends on how much you care about the mechanism. Natural pink is caused by plastic deformation of the crystal. Lab grown pink is nearly always created by irradiating a nitrogen-rich stone and annealing it, producing nitrogen-vacancy centers. The color is permanent and structural in both cases. One is an accident that took a billion years. The other is a Tuesday in a converted fruit warehouse in Wenatchee, Washington, which is where the largest lab diamond producer in the United States runs its foundry on hydropower from the Columbia River. Nobody is going to look at your hand and calculate the mechanism. They're going to look at whether it reads as a jewel or as a gumball, and that gets decided by the grade you chose and the setting you put it in.

Question 18

18. Why are natural pink diamonds so expensive?

Accepted Answer

Because the supply effectively ended. Rio Tinto's Argyle mine in Western Australia produced roughly 90 percent of the world's pink diamonds and it stopped mining on November 3, 2020, after 37 years. There is no replacement source. Everything natural and pink that exists is already above ground. For scale: the 59.60 carat Pink Star, the largest internally flawless Fancy Vivid pink GIA has ever graded, sold for $71.2 million at Sotheby's Hong Kong in 2017. It's still the record for any gem at auction. That's the ceiling, and it's why a lab grown alternative that looks natural is worth doing properly.

Question 19

19. How do I tell a real pink diamond from a fake one?

Accepted Answer

First, separate the two questions hiding inside that one. A fake pink diamond isn't a diamond at all. It's a pink sapphire, a pink CZ, a glass doublet, or a coated stone with color sprayed onto the pavilion. A coating scratches off. A sapphire has different optics and is noticeably less bright. A doublet shows a seam under magnification. A lab grown pink diamond is not fake. It's a diamond. If someone sold it to you as natural, that's fraud, and a GIA or IGI report settles the argument in about four seconds. That's why every stone we sell ships with one.

Question 20

20. What is a canary diamond?

Accepted Answer

A trade nickname for an intensely saturated yellow diamond, usually Fancy Intense or Fancy Vivid. It is not a grading term and it appears on no certificate anywhere. It's a great word. It moves product. Just know that when a retailer says canary, they're describing the vibe, and the report is describing the diamond. One of those two is legally accountable. Read the report.

Question 21

21. What makes a blue diamond blue?

Accepted Answer

Boron atoms substituting into the carbon lattice. That's it, and it's remarkable, because those same boron atoms make blue diamonds semiconductive. Blue diamonds conduct electricity. Almost no other gem does anything like that. Worth knowing: some blue diamonds on the market get their color from irradiation instead of boron, and those tend to read greenish blue. The report will say which. If a listing is silent on the subject, that silence is the answer.

Question 22

22. What does a blue diamond engagement ring mean?

Accepted Answer

Honestly? Whatever you decide it means. There's a long tradition of assigning blue stones to loyalty, trust, and eternity, most of which was carried over from sapphire symbolism and then applied to blue diamonds by people selling blue diamonds. There's no ancient tradition here. Blue diamonds were barely available to anyone until Argyle and a handful of other sources made them findable at all. What a blue diamond does mean is that you picked it. Colorless is the default. Choosing a color is a decision, and decisions are what people ask about.

Question 23

23. Why are red diamonds the rarest color?

Accepted Answer

Because red is pink with the intensity turned all the way up, and the crystal distortion that causes it is a needle-threading event. Fewer than about 30 natural red diamonds are known to exist, and most are under half a carat. The largest, the Moussaieff Red, is 5.11 carats. Most stones sold as red are graded purplish red or brownish red, because true Fancy Red is essentially a rounding error in the world's diamond supply. Lab grown red exists and it's produced the same way lab grown pink is, pushed further.

Question 24

24. What is a chocolate diamond?

Accepted Answer

A brown diamond with a trademark on it. "Chocolate Diamond" is a registered brand term belonging to Le Vian. The stone underneath is a brown diamond, and brown is the most common fancy color there is. Argyle produced them by the millions and for decades they were sold as industrial grit. That's not a reason to dislike brown diamonds. Cognac and champagne stones are genuinely gorgeous in the right setting and the right metal. It's a reason to know what you're paying for, which is a stone plus a marketing campaign.

Question 25

25. Are green diamonds real?

Accepted Answer

Yes, and natural ones are among the hardest gems on earth to certify. Natural green comes from millions of years of exposure to radiation from surrounding rock, which knocks carbon atoms out of position. The problem is that a lab can produce a nearly identical effect with an irradiation chamber in an afternoon. Distinguishing natural green from treated green is one of the genuinely difficult calls in gemology, and often the color exists only as a thin skin on the rough that gets polished away. Lab grown green is available, honest about itself, and one of the most underused colors in jewelry. Green and pink make each other better. Green and yellow do too. Personal bias, fully disclosed: a green diamond is my favorite gem in the world. Not my favorite diamond, my favorite gem, full stop. Nothing else does what a good green does in low light. I've never gotten over the first time I saw a tray of them and I don't intend to.

Question 26

26. What about gray and purple diamonds?

Accepted Answer

Both are worth your attention and both are quietly having a moment. Gray diamonds are usually hydrogen-related, and a good one has a stormy, slightly metallic quality that photographs beautifully and looks even better in person. Purple is rare in nature, typically comes with a secondary hue (purplish pink, pinkish purple), and reads as expensive without shouting. These are the colors people land on when they've gotten tired of every engagement ring looking the same. They're also colors that live or die entirely on the setting, which is the whole reason I'm in business.

Question 27

27. What is an old mine cut diamond?

Accepted Answer

The dominant diamond cut from roughly the 1700s through the late 1800s, cut entirely by hand before electricity, before saws, before optical modeling. The signatures: a squarish cushiony outline, a small table, a tall crown, a deep pavilion, and a large open culet that looks like a little window when you stare straight down into the stone. Cutters followed the shape of the rough to save weight, so every one is slightly different. It's the direct ancestor of the modern round brilliant, and it behaves nothing like it.

Question 28

28. What's the difference between an old mine cut and an old European cut?

Accepted Answer

Chronology and outline. Old mine cuts came first and are cushion-shaped, following the natural octahedral rough. Old European cuts came later, once bruting machines allowed a truly round girdle, and they're round with a smaller culet and a slightly more organized facet pattern. Both are hand cut. Both have the high crown and small table that make the light behave the way it does. Old mine is the more irregular, more romantic, more idiosyncratic of the two.

Question 29

29. Why do old mine cuts look so good in candlelight and restaurant lighting?

Accepted Answer

Because they were designed for it, whether the cutters thought of it that way or not. A modern brilliant is optimized to return a huge number of tiny, rapid flashes under bright overhead light, which is exactly the lighting condition in a jewelry store and almost nowhere else in your life. An old mine cut has larger facets, so it returns fewer, bigger, slower flashes. In dim warm light it glows and blinks instead of glittering. You wear jewelry at dinner and at parties, not under a jeweler's halogen. The old cuts understood the assignment 250 years early.

Question 30

30. Can you get a lab grown old mine cut diamond?

Accepted Answer

Yes, and it's one of the best things to happen to jewelry in the last decade. A natural old mine cut has to be found. The supply is fixed, because nobody has hand cut a diamond this way since electricity, and antique stones command a premium that has nothing to do with the diamond and everything to do with there being a finite number of them. Want a specific size, a specific outline, a clean stone, and a culet you actually like? Get in line behind the collectors and bring a wire transfer. A lab grown old mine cut is cut fresh, to the antique proportions, from a stone that didn't exist two months ago. Same geometry, same small table, same tall crown, same open culet, same glow. The difference is that you can specify it instead of hunting it. You get the cut you fell in love with at the size you want, and you get it this season instead of after a three-year search.

Question 31

31. Is a lab grown old mine cut "authentic"?

Accepted Answer

Depends on what you're buying it for. If you want a specific object that a specific person held in 1840, no lab stone will ever give you that, and you should go buy an antique. Provenance is real and I respect it. If what you love is the way the cut behaves, the geometry, the glow, the big lazy flashes, then a lab grown old mine cut delivers the exact same optical performance, because optical performance comes from proportions and material. It's carbon in the same arrangement, cut to the same angles. The light doesn't check the birth certificate.

Question 32

32. Do old mine cuts sparkle less than modern diamonds?

Accepted Answer

They sparkle differently, and yes, less brightly under a spotlight. That's the point. Modern round brilliants are engineered to maximize measurable light return. If you put a modern round and an old mine cut side by side under a display case light, the modern stone wins and it isn't close. Move both to a candlelit table and the old mine cut is the one you can't stop looking at. One is optimized for the sale. The other is optimized for the next forty years.

Question 33

33. Does an old mine cut look smaller than a modern diamond of the same carat weight?

Accepted Answer

Slightly, yes, and it's worth knowing before you shop. Carat is weight, not size. An old mine cut carries more of its weight below the girdle in that deep pavilion, so a two carat old mine cut faces up a touch smaller than a two carat modern brilliant. If you're optimizing for the biggest possible number of millimeters per dollar, the modern cut wins. Nobody has ever fallen in love with a diamond because of its millimeters per dollar. What you get back for those fractions is the depth, the glow, and the fact that nobody else at the table has one. That trade takes about four seconds to make once you've seen the stone in person.

Question 34

34. Why is the culet open on an old mine cut?

Accepted Answer

Two reasons, one practical and one aesthetic. Practically, a fine point at the bottom of a hand-cut diamond is a chip waiting to happen, and a cutter working without modern tooling protected the tip by faceting it flat. Aesthetically, the open culet is what gives you that little dark hexagon when you look down through the table, which people either love or find unnerving. I love it. It's the fingerprint of a cut made by a person rather than a machine.

Question 35

35. Are old mine cuts durable enough for an engagement ring?

Accepted Answer

Yes, with sane setting choices. It's a diamond. It's still a 10 on the Mohs scale. The two things to respect: the open culet sits lower in the stone than you'd expect and shouldn't be left exposed against a hard surface, and the high crown means the stone sits taller, so it catches on sweaters if it's set carelessly. Both are setting problems, and setting problems are solvable by whoever designed the setting. Every piece we build accounts for the specific stone's proportions. That's most of what the design process actually is.

Question 36

36. How much do lab grown fancy color diamonds cost, and why does a finished piece cost more than a loose stone I found online?

Accepted Answer

Loose stones are a commodity market and the pricing moves constantly, driven by color, size, intensity, and how many people are growing that color that quarter. Finished Every Stone pieces start around $5,000. Those two numbers are not comparable, and I'd rather say that out loud than let you discover it in a shopping cart. A loose stone is an ingredient. The price of a finished piece covers the stone, the metal, the design work, the casting or fabrication, the setting, the finishing, and the fact that the setting was conceived around that specific diamond's color and proportions and then never made again. You can absolutely buy a loose lab grown yellow and have it dropped into a stock head somewhere for less money. It will look like every other lab grown yellow dropped into a stock head. That's the market we exist in opposition to.

Question 37

37. What would one of these stones cost if it were natural? Do the math for me.

Accepted Answer

Happily, because the numbers make my argument better than I can. Everything below is retail, current as of July 2026, and every example is three carats, because that's the size we work in. Example one: a three carat old mine cut. A natural antique old mine cut at three carats runs roughly $40,000 for the stone alone, and that's in the color you'd actually find, which is warm. There's a four carat antique on the market right now at $38,950, GIA graded SI1, S color. If you want a three carat antique in E color and VS clarity, the honest answer is that it basically doesn't exist. Those stones were cut by hand in 1860 from whatever rough was sitting on the bench, and nobody was sorting for E. A lab grown old mine cut at three carats, E color, VS2, IGI certified, is $2,149 at retail. Same geometry, same small table, same tall crown, same open culet, better color and clarity than the antique, at about five percent of the price. Now the part everyone skips. Natural diamonds resell for roughly 25 to 50 percent of retail. Lab grown resells for roughly 10 to 30 percent, and sometimes nothing at all. Natural: paid $40,000, gets back $10,000 to $20,000, loses $20,000 to $30,000. Lab grown: paid $2,149, gets back $215 to $645, loses about $1,500 to $1,900. The natural buyer has the better percentage and the worse morning. They spent roughly $25,000 to demonstrate a superior recovery rate. The lab buyer lost about the cost of a decent mattress and wore the same cut on their hand the whole time. Example two: a three carat radiant, Fancy Vivid Yellow. A natural three carat Fancy Vivid Yellow is about $75,000 for the stone. For reference, a two carat Fancy Vivid Yellow radiant ring is on the market at $78,500 right now, and a 3.07 carat Fancy Intense Yellow, one full grade down in saturation, is listed at $90,000. A lab grown 3.08 carat Fancy Vivid Yellow radiant is $5,720 at retail. Not a typo, and not a cheap stone by lab standards either. Fancy color at size is genuinely harder to grow than the colorless goods everyone quotes at four hundred dollars. Natural fancy colors resell better than colorless, so let's be generous and say 40 to 60 percent. Natural: paid $75,000, gets back $30,000 to $45,000, loses $30,000 to $45,000. Lab grown: paid $5,720, gets back $570 to $1,720, loses about $4,000 to $5,150. The natural yellow buyer lost roughly eight times more money. Across a dinner table, the two rings look like the same ring. Example three: blue diamond, which is where the natural argument is strongest and least useful. Blue actually appreciates. That's not marketing, it's the data: fancy color index figures have blues up 244 percent since 2005. If you're going to make the investment case for a colored diamond, blue or green is where you make it. So here's the entry fee. Natural fancy blue runs $30,000 to more than $500,000 per carat depending on the grade, and at three carats a Fancy Vivid Blue crosses a million dollars per carat. The three carat blue in this comparison is a three million dollar stone. For scale, the 14.62 carat Oppenheimer Blue sold for $57.5 million in 2016, roughly $3.9 million per carat. A lab grown blue runs somewhere between $500 and $2,000 per carat, which puts the same look at three carats in the low thousands. Yes, the natural blue appreciates. To find out, you need three million dollars in cash, parked in a rock, doing nothing, in an asset you can't sell on a Tuesday. It pays no dividend, it has no bid, and the day you buy it at retail you're already underwater against the wholesale market it actually trades in. You'll get your money back eventually, probably, if you hold it for twenty years and find the right buyer and the market cooperates. If you have three million dollars and you want that trade, take it. I'm not being sarcastic. It's a real asset and it has outperformed most things. But that's a portfolio decision wearing a ring costume, and almost nobody reading this page is making it. Most people want a blue diamond on their hand at dinner. There's another way to get there. Two honest caveats, because I'd rather you trust me than agree with me. Resale percentages are ranges, not promises, and they swing on the buyer, the paperwork, and the day of the week. And the natural stones in all three examples are genuine assets with genuine markets. I'm not pretending otherwise. I'm pointing out that a genuine market with a fifty percent haircut on a $75,000 purchase is still a $37,500 hole in your life, and no percentage on earth fills it back in.

Question 38

38. Do lab grown diamonds hold their value?

Accepted Answer

No, and neither does almost any jewelry you buy at retail. Here's the part the natural diamond industry doesn't advertise: walk into any jeweler with a natural one carat colorless diamond you paid $8,000 for and see what they offer you. The resale market for mass-market natural diamonds is brutal and always has been. The "investment" framing was invented in an ad campaign. Lab grown is worse in percentage terms and much better in dollar terms, which is the only term that spends. See the math above if you want it in numbers. Genuine appreciation lives in a narrow band: Argyle pinks, fancy vivid blues and greens, historic stones, exceptional naturals with paperwork. That market is not where anyone reading this is shopping, and it isn't where I'm selling. Buy jewelry because you want to wear it.

Question 39

39. Do colored diamonds depreciate at the same rate as colorless diamonds?

Accepted Answer

No. This is the strongest argument the natural side has, so it deserves the real numbers rather than a dodge. The Fancy Color Research Foundation tracks wholesale fancy color prices. In 2024 its index fell 2.2 percent, the steepest annual drop since the index launched in 2014. In the same year, white diamond prices fell 13.3 percent. That's a six-fold difference, and it's the entire basis for calling fancy colors a safe haven. Zoom out and it looks better still. Going back to 2005, FCRF data has pinks up 394 percent, blues up 244 percent, and yellows up 50 percent, with the category compounding at roughly 5.7 percent a year over twenty years. Now the two things nobody quotes at you. First, yellow is the soft spot of the category. Yellows fell 5.6 percent in 2024 and 6.1 percent over the trailing twelve months into Q1 2025, and the three carat Fancy Intense Yellow specifically dropped 3 percent in a single quarter. The color everyone reaches for as their entry into fancy color is the color doing the worst. Second, and this is the big one: that index is wholesale. You bought at retail. You will sell into wholesale. That gap swallows the index whole. A stone can be up 5 percent on the index and still hand you a 50 percent loss, because the index was never measuring your transaction in the first place. So the ranking is real: natural fancy colors hold up better than natural colorless, which holds up better than lab grown. All three lose you money at retail. The only variable is how much, and it scales with what you paid. Blue is the one color where the appreciation case genuinely holds, and the price of admission is in the previous answer.

Question 40

40. Are lab grown diamond prices going to keep falling?

Accepted Answer

Colorless lab grown prices have fallen off a cliff and will probably keep drifting down, because growing colorless diamonds is now a solved manufacturing problem and manufacturing problems get cheaper forever. Fancy colors behave differently. The yields are lower, the treatment steps add cost and failure rates, and a genuinely well-colored stone in an unusual hue is still not something you can order by the kilo. Old mine cutting is another constraint entirely, because it's slow, wastes weight, and requires a cutter willing to do it. None of which is a reason to buy for price appreciation. See the previous three answers.

Question 41

41. Is a colored diamond a good investment?

Accepted Answer

I'm a jeweler, not your financial advisor, so treat this as an opinion rather than advice. Natural fancy colors have historically outperformed most other gems, and Argyle pinks in particular have appreciated substantially since the mine closed. That's a real market with real auction records behind it, and it requires six or seven figures, a wholesale relationship, and a long horizon to participate. If that's you, buy natural and buy the best stone you can find. A lab grown piece is not that trade and I won't sell it as one. It's a piece of jewelry that will look extraordinary for the rest of your life and that you can afford to actually wear instead of insuring and hiding. That's the return.

Question 42

42. Should I insure my piece, and do you provide an appraisal?

Accepted Answer

Yes, insure it. Most homeowner's and renter's policies cap jewelry coverage at a number far below what you just spent, and a scheduled rider or a specialist jewelry policy costs a fraction of what people expect. Every piece ships with its IGI or GIA report, which is what an insurer will ask for first. If you need an appraisal for coverage purposes, contact me and I'll help you get one from an independent appraiser.

Question 43

43. Why does the setting matter so much for a colored diamond?

Accepted Answer

Because color is relational, and every serious fancy color collector has known this for a century. Pink and green make each other better. Blue and pink do. Green and yellow do. The metal underneath a stone changes how much color reaches your eye. The proportion of surrounding stones changes whether the center reads as saturated or washed out. A setting is a color instrument. The standard industry move is a prong solitaire or a generic halo, and that's the end of the creative process. It's the equivalent of buying a great cut of meat and boiling it.

Question 44

44. What metal should a colored diamond be set in?

Accepted Answer

It depends entirely on the stone, which is a boring answer, so here's the useful version. Rose gold behind a pink stone pushes the color warmer and stronger, which is either exactly what you want or the thing that tips it into looking dyed. Yellow gold does the same for yellows. Platinum and white gold stay neutral and let the stone argue for itself, which is riskier and more honest. The mistake is deciding the metal before you've looked at the diamond. I decide it last.

Question 45

45. What does "one of a kind" actually mean here?

Accepted Answer

It means the piece you're looking at is the only one of that piece. One stone, one setting, one time. I am not making five of the exact same diamond in the exact same setting and calling each one special. When it sells, that piece is gone, and refreshing the page won't bring it back. If you see something you love, grab it. What I will do is revisit a design. If you saw a ring on the site or on my social profiles and it sold before you got there, tell me, because that design can be built again. It will be built around a different stone, which means different color, different proportions, different character, and the setting gets adjusted to suit it. It'll be yours instead of a copy of hers. So: the design can come back. The diamond can't. That's the honest version, and it's a lot more useful to you than a brand promising uniqueness it has no intention of honoring.

Question 46

46. Do you do custom pieces?

Accepted Answer

Yes. If you have a stone in mind, a piece you've been picturing for years, or an heirloom you want reconceived, use the Inquire page and tell me about it. Custom work requires a deposit, takes time, and is final sale once design or sourcing begins, because by then the piece exists only for you. I'd rather tell you that up front than in the fine print.

Question 47

47. What comes with my piece?

Accepted Answer

The piece, its Every Stone packaging, and its IGI or GIA certificate for the center stone. The certificate is linked on the product page too, so you can read it before you buy rather than after. If you want me to walk you through what's on it, including the treatment disclosure line, ask. That's a conversation I enjoy.

Question 48

48. Can I have a piece resized?

Accepted Answer

Contact me before you purchase. Some pieces resize easily and some don't, depending on the setting, the stone layout, and how the shank is constructed. The important part: once a piece has been altered or resized it's no longer returnable, so we sort out sizing before anything gets cut.

Question 49

49. Do you ship internationally?

Accepted Answer

Not currently. Every Stone ships within the United States only. All orders go out fully insured and require a signature on delivery. If you're outside the US and there's a piece you want, reach out anyway. I'd rather hear from you and say no than not hear from you.

Question 50

50. Why do pieces sell out, and what is The Insider?

Accepted Answer

Because there's exactly one of each of them. Every Stone releases in limited drops. Every piece is made once. When a piece sells, it's gone permanently, which means the pieces you're seeing on the site right now are a snapshot, not a catalog. The Insider is the email list. Insiders see each collection before it goes live and get first access before the public. It's free, and given how this works, it's the difference between seeing a piece and owning it.

Question 51

What is the Smarter Way to Own an Old Mine Cut Diamond in 2026

Accepted Answer

An old mine cut diamond is a hand faceted, antique shape known for its high crown, small table, and warm, candlelit glow instead of the sharp brilliance of a modern round.Natural supply is genuinely shrinking, since most surviving stones were recut into modern shapes decades ago. A lab grown old mine cut diamond gives you the same proportions and the same optical character, made to order instead of hunted down and hoped for.

Question 52

Why Do Old Mine Cut Diamonds Look So Different From Modern Diamonds?

Accepted Answer

They look different because they were cut by hand for candlelight and gaslight, not for the fluorescent lighting and phone flashlights we judge stones under today. Cutters in the 1700s and 1800s built these stones around a specific set of proportions:  A high crown that catches and holds light instead of releasing it instantly  A small table that limits how much white light passes straight through  A large, visible culet, often left open rather than polished to a point  Facets cut and polished entirely by hand, so no two are perfectly identicalThat combination throws warm, broken flashes of light rather than the sharp, uniform brilliance a modern round brilliant is engineered to produce. GIA does not even apply its standard cut grading scale to this shape, because the scale was built for modern proportions it was never trying to hit. Judging it against a modern ideal cut is like judging an oil painting against a photograph, two tools built for two entirely different jobs.

Question 53

Why Are Natural Old Mine Cut Diamonds So Hard to Find?

Accepted Answer

A stone in genuinely good condition, meaning good color, minimal chipping, and untouched proportions, regularly commands a real premium over an equivalent modern diamond at auction, and that premium is a function of scarcity, not size. This is where a lot of buyers get tripped up. A lower price almost always means one of these:  Heavy fluorescence that dulls the stone in daylight  Visible chips or wear at the culet or facet edges  A stone that has already been partially recut and lost its original characterA lower price rarely means a smarter purchase when the stone underneath it is not what you actually wanted.

Question 54

Is a Natural Old Mine Cut Diamond a Good Investment?

Accepted Answer

No, and the math makes that clear fast, especially at this size. Say you pay 45,000 dollars for a natural, three to four carat old mine cut diamond in solid condition, whether that is through an estate jeweler or at auction with the buyer's premium included. That figure is what it actually costs you, retail. Try to sell it later and you are no longer the one setting the price. A dealer is, and dealers buy at wholesale, typically 40 to 60 percent of what a stone last sold for, which puts a real 18,000 to 27,000 dollar loss on a stone that never left the box and never changed at all.Now compare that to a lab grown old mine cut diamond at the same size. The stone itself runs around 6,000 dollars retail, and a finished, one of a kind piece built around it still lands nowhere near the natural retail figure, without any of the resale fiction attached to it. The premium on a natural old mine cut diamond comes from scarcity and craftsmanship, not from any documented track record of the stone appreciating in value. Paying more buys rarity, not proven upside.If the goal is owning a piece you genuinely love, a natural one can absolutely be that. If the goal is treating it like an investment, the math does not support it.

Question 55

Can You Just Recut a Modern Diamond Into an Old Mine Cut?

Accepted Answer

You can, but you will lose meaningful carat weight in the process and you still will not own a genuine antique stone. A recut can approximate the look, but it cannot replicate the history, and the scarcity problem simply shifts from the seller's side to yours. If the appeal was ever about owning something with real age behind it, a recut modern stone was never going to deliver that regardless of how well it is cut.

Question 56

What Is a Lab Grown Old Mine Cut Diamond?

Accepted Answer

A lab grown old mine cut diamond is a diamond grown in a controlled lab environment and then hand faceted into the same high crown, small table, open culet proportions as an antique original, without depending on a hundred year old stone having survived intact. It is chemically, physically, and optically identical to a natural diamond of the same cut, confirmed by GIA and IGI using the same equipment they use on natural stones. The only differences are origin and price. That means the same warm, broken light pattern collectors love, produced today, cut to order, at a fraction of what a genuine antique commands at auction.

Question 57

Is a Lab Grown Old Mine Cut Diamond a Real Old Mine Cut?

Accepted Answer

Yes, and honestly, for most buyers it is the smarter version of the same thing. A cut is a cut. The proportions that define it, the high crown, the small table, the large culet, the hand faceted asymmetry, do not depend on where the carbon came from. Here is what you get with this option that you do not get with a natural one:  No gamble on undisclosed fluorescence, chips, or a partial recut hiding under a pretty description  No competing against collectors and estate dealers for a shrinking pool of supply  A price that reflects the cut and the craftsmanship, not a hundred years of survivorship luck  The exact proportions you want, cut to order, instead of whatever happened to surviveIt is faceted by the same techniques and held to the same standards as a natural one. The only thing you are giving up is a scarcity story. Everything about how the stone performs, looks, and wears stays exactly the same.

Question 58

How Every Stone Approaches the Old Mine Cut Diamond

Accepted Answer

Every stone we build a piece around is one of a kind. We do not drop it into a generic prong setting and call it done. Each setting is designed around that specific stone, the same intention historically reserved for jewelry houses working with natural antiques that cost many multiples more

Question 59

Why Do Lab Grown Pink Diamonds Look Fake?

Accepted Answer

Because they are grown and treated to hit the loudest color grades, Fancy Intense and Fancy Vivid, at carat weights where those grades barely exist in nature. Across the entire history of the Argyle tender, the single greatest source of pink diamonds on earth, only ten stones ever exceeded three carats. Search for a four carat vivid pink today and you will get pages of them. The diamond is real. The combination of size and saturation is what your eye is rejecting, and it is rejecting it correctly.

Question 60

Are lab grown pink diamonds real diamonds?

Accepted Answer

Yes. A lab grown pink diamond is carbon crystallized in the same cubic lattice as a mined diamond, with the same hardness of 10 on the Mohs scale. It is not cubic zirconia. It is not moissanite. It is not a simulant of any kind. A trained gemologist needs specialist equipment to separate one from a mined stone, and the only meaningful difference is where it came from.when people say a pink diamond ring "looks fake," they almost never mean they suspect glass. They mean it looks cheap. Those are different complaints with different causes, and the second one has a real answer that nobody in this category wants to give you.I will give it to you.

Question 61

So why do lab grown pink diamonds look fake?

Accepted Answer

Three things, and they compound.The size and the color grade are a combination that essentially does not occur in nature, and some part of your brain already knows it.The pink itself arrives by a completely different physical route than natural pink, and that route leaves a visual signature.The stone gets dropped into a setting that was designed for nothing in particularThe first one is the most important, and it is the one nobody talks about.

Question 62

How rare is a large, vivid natural pink diamond?

Accepted Answer

Rarer than almost anyone shopping for one understands. Here is the math.The Argyle mine in Western Australia produced more than 90% of the world’s pink diamonds until it closed in 2020. The numbers coming out of it looked like this:About 20,000 carats came out pink, from roughly 130 million carats mined annually. That is 0.01%. After the material lost in cutting, the entire planet got somewhere around 9,000 polished carats of pink diamond per year. The majority of those pinks were under 0.08 carats. That is melee, the size used to decorate a center stone rather than be one. The average Argyle stone left the mine at around 0.10 carat.Gather every Argyle pink above half a carat produced in a given year and you could hold all of them in one hand.Once a year, Argyle selected its 40 to 60 finest stones for the tender, an invitation-only sale for about 150 buyers worldwide. The best of the best, cherry-picked from an entire year of production.Leibish analyzed every tender ever held. Of roughly 1,277 stones offered across the tender’s entire history, ten were above 3.00 carats. Ten. That is 0.78%. Exactly one year, 2001, produced a stone above 4 carats: a 4.15 carat Fancy Intense Purplish Pink. Not vivid. Intense.Three decades. The greatest pink diamond source that has ever existed. Hand-selecting its fifty best stones every year. Ten stones over three carats, total.Now go type "pink diamond ring" into Google and count the three and four carat vivid pinks staring back at you from the shopping grid.For scale, here is what the real ones costThe Williamson Pink Star, 11.15 carats, Fancy Vivid Pink, Internally Flawless, sold at Sotheby’s Hong Kong in October 2022 for $57.7 million. That is roughly $5.18 million per carat, a world record price per carat for any diamond or gemstone. The CTF Pink Star, 59.60 carats, Fancy Vivid Pink, sold for $71.2 million in 2017 and remains the most expensive jewel ever sold at auction. Those stones are your brain’s reference library for the phrase "vivid pink diamond." So when a four carat vivid pink shows up in your feed for the price of a used Corolla, you do the math without anyone asking you to. You may not be able to articulate why it looks wrong. It looks wrong anyway.

Question 63

Where does the pink in a lab grown diamond actually come from?

Accepted Answer

This is where it gets genuinely interesting, and where every retailer in the category goes quiet.GIA researchers studied a sample of 1,000 pink diamonds and confirmed that in 99.5% of them, the color comes from distortion in the crystal structure itself, not from a trace element. Nitrogen makes a diamond yellow and boron makes it blue, but pink is not a chemistry story at all. The crystal got physically squeezed and warped under enormous pressure, and the warping bends light into pink. In natural pinks that color concentrates in narrow parallel bands called glide planes, or pink graining, and cutters orient those lines perpendicular to the table to push the body color as far as it will go.That is why a fine natural pink has depth. The color is uneven. It has grain, it has shadow, it moves as the stone moves.Lab grown pink works nothing like that. According to GIA’s Sally Eaton-Magaña, the most common method by a wide margin is to take a lab grown diamond that was grown with nitrogen impurities, irradiate it, then heat it to somewhere between 600 and 1000 degrees Celsius. That creates negatively charged nitrogen-vacancy centers, and those NV centers are what produce the pink.And here is the sentence that should end the conversation: GIA’s researchers state there is no known method of replicating plastic deformation and its 550 nm absorption band through any laboratory treatment or growth process. None. Not with current technology.Two different roads to the same word on a certificate, and the road shows in the stone.Natural pink: color created by physical distortion of the crystal, concentrated into narrow bands. Uneven, grained, full of depth. It moves as the stone moves. Lab grown pink: color created by NV centers after growth, distributed evenly through the entire stone. No graining, no zoning, no movement. A flat wall of pink.It gets worse when you push it. GIA lab notes on treated pink CVD material describe stones grading out as Fancy Deep brownish orangy pink and Fancy brown-pink, with the pink and the orange both traced to the same NV absorption behavior. GIA has also documented treated pink material with a visibly mottled face-up appearance. Crank the mechanism and it drags a secondary color along for the ride, which is exactly why so much of this jewelry has a faint highlighter quality you cannot quite name.

Question 64

Are lab grown pink diamonds treated?

Accepted Answer

Almost always, yes, and there is nothing wrong with that as long as it is disclosed. IGI reports on lab grown diamonds specify whether a stone is "as grown with no indication of post-growth treatment" or whether it "may include post-growth treatment." Ask for the report. Read the comments section, not just the color line. A seller who hands over the certificate without flinching is telling you something. So is one who does not.
