Lab-Grown vs Natural Diamond Resale Value: The Honest Truth

This is the most searched question in the lab-grown diamond debate. Here is the real data without spin from either side.

Lab-Grown Resale
10-30%
of original purchase price
Natural Resale
20-50%
of original purchase price

Why Does the Gap Exist?

The resale gap exists because of supply economics. Natural diamonds are finite. A 1-carat natural diamond from 2020 competes in the resale market with other natural diamonds from finite geological sources. New supply does not undercut existing supply dramatically because the total pool of mined diamonds grows slowly.

Lab-grown diamonds face a different problem. A 1-carat lab-grown from 2020 competes with 2026 production that is significantly cheaper due to improved manufacturing efficiency. A secondhand 2020 lab-grown diamond is worth less because a brand-new equivalent stone costs less today than it did then. As production technology continues to improve, this dynamic is likely to intensify.

Even accounting for the resale value gap, a lab-grown diamond costs less over its lifetime because the purchase price difference is so large. This analysis assumes you actually sell the diamond, which most buyers never do. If you keep the ring, the resale value question becomes entirely theoretical.

Resale Value FAQs

Do lab-grown diamonds hold their value?
Lab-grown diamonds have lower resale value than natural diamonds. Lab-grown stones typically resell for 10-30% of the original purchase price, while natural diamonds typically resell for 20-50%. The gap exists because lab-grown supply is unlimited and growing, while natural diamond supply is finite. Neither type is a good financial investment compared to financial assets.
Can you sell a lab-grown diamond?
Yes, but options are limited compared to natural diamonds. Most jewellers will not buy back lab-grown diamonds. Online resale platforms like Worthy, I Do Now I Don't, and eBay are better options. Expect to receive 10-30% of the original purchase price. The resale market for lab-grown diamonds is less developed than for natural diamonds but is slowly growing.
Are lab-grown diamonds worth anything?
Yes. Lab-grown diamonds have real monetary value and can be resold. However, they depreciate significantly from retail purchase price, typically to 10-30% of what you paid. This is similar to how most luxury goods depreciate when resold. Natural diamonds also depreciate, typically to 20-50% of retail price on the secondary market.
Is a diamond a good investment?
Neither lab-grown nor natural diamonds are good financial investments for most buyers. Both lose significant value from retail purchase price when resold. If investment return is your goal, financial assets like index funds, real estate, or collectibles with established secondary markets are better options. Buy a diamond because you love it, not as a financial strategy.
