Do Lab-Grown Diamonds Hold Their Value? What Buyers Should Know

Last updated: October 17, 2026

Quick answer: No diamond, lab-grown or natural, should be treated as a financial investment. Both typically resell for a fraction of their original retail price, since retail prices include the brand's design, craftsmanship and service, not just the raw stone. Lab-grown diamonds specifically have also become significantly less expensive to produce in recent years as the technology has scaled, which has pushed their resale value down faster than natural diamonds. Most people choose a lab-grown diamond because it lets them buy a larger or higher-grade stone for their budget and because it is a real diamond they'll enjoy wearing, not because they expect it to appreciate. This is general information, not financial advice; if resale value is a priority for you, consult a qualified financial advisor.

Why diamonds, in general, aren't a good investment

Retail diamond jewelry prices reflect far more than the raw stone: design, craftsmanship, certification, marketing, and the retailer's margin are all built into the price you pay. When you resell a piece, a buyer (whether a private individual or a dealer) is typically only willing to pay close to the wholesale value of the stone itself, not the retail price you paid. This is true of natural diamonds as well as lab-grown ones, and it's also true of most retail jewelry in general, including gold jewelry once you account for the craftsmanship built into the price beyond the raw metal value.

Why lab-grown diamonds specifically have softened in resale value

Lab-grown diamond production technology has matured quickly, and production costs have fallen as more labs have scaled up. This has made lab-grown diamonds more affordable to buy new, which is good news for buyers, but it also means older lab-grown stones can be resold for less than what was originally paid, since new production is often cheaper and more widely available than when the stone was first purchased.

What does hold value in a diamond or colored diamond

• Rarity. Natural fancy color diamonds, especially in strong intensities like Fancy Vivid, are genuinely rare in nature, which is part of why they carry significant premiums over lab-grown stones of the same color. See our colored diamond price guide for real data on this gap.
• Certification. An independently graded stone with a verifiable report is easier to resell with confidence than an uncertified one. See our certification guide.
• Condition and craftsmanship. A well-maintained piece in solid gold, properly cared for over the years, generally holds its appeal better than a neglected one. See our jewelry care guide.

So why buy a lab-grown diamond at all?

Because it's a real diamond, chemically and optically identical to a natural one, at a lower price, which means you can choose a larger stone, a higher color and clarity grade, or a stronger color intensity for the same budget. Most people buying an engagement ring or fine jewelry are buying something to wear and enjoy for decades, not an asset to trade, and lab-grown diamonds are an excellent choice for exactly that purpose.

If resale matters to you

If you specifically want to preserve resale value as much as possible, a natural diamond with strong certification from a major lab (GIA, IGI or SGL) will generally hold a higher proportion of its value than a lab-grown stone, though still well below its original retail price. This is a personal budget and priorities decision, not a right-or-wrong one, and it's worth being clear-eyed about rather than assuming either option is a financial investment.

Frequently asked questions

Do lab-grown diamonds hold their value?

Not reliably. Like natural diamonds, lab-grown diamonds typically resell for well below their original retail price, and falling production costs have pushed resale values down further in recent years.

Are lab-grown diamonds a good investment?

No. Neither lab-grown nor natural diamonds should be treated as a financial investment. This is general information, not financial advice.

Do natural diamonds hold value better than lab-grown diamonds?

Generally yes, natural diamonds tend to retain a higher proportion of their original price than lab-grown diamonds, largely due to their relative rarity, though both typically resell below retail price.

Why do people buy lab-grown diamonds if they don't hold value?

Because they are real diamonds at a lower price, letting buyers choose a larger stone or stronger color for their budget, purchased to wear and enjoy rather than to resell.
