Do Lab Grown Diamonds Hold Their Value? The Honest Resale Data

No, and it helps no one to pretend otherwise. A lab grown diamond bought at retail typically returns about 20 to 30 percent of its purchase price if you sell it for cash, and the honest range across the market runs from 10 to 40 percent depending on the stone and the buyer.¹ A natural diamond recovers more, around 50 percent and occasionally higher, but that is still half of what you paid.⁷ Neither holds its value in the way jewellery marketing has implied for a century.

The important move is not to soften that figure. It is to put it in context. Lab grown resale is low because new lab grown prices keep falling, which is the same force that lets you buy a larger, cleaner stone today for a fraction of the natural price. The weakness on the resale side and the strength on the purchase side are the same phenomenon read from two ends.

Yes, but understand the three routes out, because they pay very differently. Cash resale on the secondhand market is the fastest and the lowest. Trade in credit at the original retailer shows a higher number on paper but locks you into that store. Private peer to peer sale can fetch the most cash but is slow and unreliable, because there is no established buyer for used lab grown stones.¹

The pattern is the same for both origins. The nominal trade in number is always the friendliest, because it is credit rather than cash and it commits you to spending more. The cash number is always the truth. For lab grown, that cash number sits near a third of purchase at best, because the resale market itself is thin. There is no liquid secondary exchange for used lab grown diamonds, and the absence of that infrastructure is a large part of the story.¹

Because the new price keeps falling, and a used stone has to compete with it. This is the whole mechanism, and it is worth stating precisely. Paul Zimnisky priced a generic one carat VS1, G colour lab diamond at about $3,625 in 2018. By his 2026 analysis, the same specification sold new for about $1,615, a fall of roughly 55 percent.¹ No used stone can hold a floor when the identical new stone gets cheaper every year.

The wholesale data tells the same story from the supply side. Edahn Golan reported lab grown wholesale prices down 26 percent across 2025, with the fourth quarter drop slowing to 4.7 percent, the smallest since the market began.² Into 2026 the declines eased further, down about 14 percent year over year in the first quarter and roughly 13 percent in the second.³ The fall is decelerating, which points to stabilisation near a production cost floor rather than a recovery.

The structural drivers reinforce each other. Production cost has fallen toward rough material at roughly ten dollars a carat, supply is effectively unlimited because a stone can be grown on demand, and there is no scarcity to defend a price. For the full picture of that decline, see the lab diamond price collapse report. None of this is a flaw in the diamond you wear. It is simply why resale cannot work the way people expect.

On the recovery rate, yes. On the premise, no. A natural diamond returns around 50 percent of purchase against a lab stone's 20 to 30, roughly double the rate.⁷ But that rate is applied to a much higher price you paid in the first place, and the natural number is itself sliding. Natural diamond prices fell about 20 to 30 percent between 2022 and 2025. One caratX example put a one carat D, VVS2 stone at about $8,000 in early 2022 and roughly $5,500 by late 2025.⁷

So the honest framing is not lab grown weak, natural strong. It is that the idea of a diamond as a store of value has thinned for both, just faster for lab grown. BriteCo's market work shows the scale of the gap on the purchase side: an average one carat lab diamond around $1,000 or less in 2025 against a natural one carat averaging about $4,200.⁵ You recover half of the natural price, but you paid four times as much to get there.

Trade in programs look generous and pay nothing in cash. Take the most cited example. Brilliant Earth's lifetime upgrade program gives lab grown owners credit equal to the original purchase price, but only toward a new lab diamond of at least twice the value. Natural owners get the same original price credit toward a stone of at least one and a half times the value.⁶ Read that carefully. It is store credit, not money back, and it only unlocks if you spend more.

The structure favours the retailer by design. Because the credit is pegged to the original nominal price rather than today's much lower replacement cost, and because the falling market means the returned stone is worth far less than the credit, the store carries little risk while you commit to a larger purchase. Cash buyback offers are the clearer signal of real value, and independent buyers typically pay around 30 to 50 percent of current retail, not of what you originally paid.⁹ A trade in is an upgrade mechanism. It is not a way to get your money out.

This is where the value question resolves in your favour. Jewellery insurance never pays resale value or sentimental value. It reimburses documented replacement value, the cost to rebuild the same piece new today.⁴ For lab grown that is a meaningful protection, and because replacement cost keeps falling, your coverage need shrinks over time rather than growing.

BriteCo sets the sum insured by appraisal covering carat, cut, colour, clarity, growth method, and setting, and covers up to 125 percent of appraised value with zero deductible. Typical jewellery premiums run about 0.5 to 1.5 percent of appraised value a year. Because lab grown prices move faster than mined, reappraise every two to three years so the coverage and the premium track the real replacement cost.⁴ For the appraisal detail, see the lab diamond insurance and appraisal guide. You insure against loss of the piece, not against a market position, which is exactly the right way to hold it.

If you are buying a resale asset, buy neither lab grown nor natural, because a diamond is a poor one either way. If you are buying a stone to wear, lab grown is the stronger choice, and the falling prices that hurt resale are the reason. You pay 60 to 80 percent less than the natural equivalent and get roughly two to three times the carat and quality per dollar today.¹ The honest trade is simple. You accept near zero recovery in exchange for a larger, cleaner stone now, and you were never going to sell a ring you love.

What protects the money is not a resale floor. It is buying the right specification once, at a fair price, with independent certification and a guarantee behind it. Every Draco diamond is IGI certified, E to F colour, VS2 and better, and priced direct, up to 64 percent below Blue Nile and up to 52 percent below James Allen for comparable stones. If you already have a quote from another retailer, the fastest way to test that is to bring it to us.

The value of a lab grown diamond was never going to be found on a resale receipt. It is in the years you wear it, the size you could actually afford, and the certainty that you did not overpay to begin with. That is the number that matters, and it is the one you control.
