Do Lab-Grown Diamonds Hold Their Value? Resale and Investment

It is one of the most common questions about lab-grown diamonds. Do they hold their value? Will they be worth anything in ten, twenty, or fifty years? Are they an investment, or just a beautiful expense?

This article answers those questions honestly, without marketing spin or wishful thinking. Because you deserve the truth, even when it is nuanced.

The Short Answer

Lab-grown diamonds currently have a lower resale value than mined diamonds. This is a fact, and we state it openly.

But the full picture is more complex than a simple comparison. The resale value of all diamonds — mined or lab-grown — is far lower than most consumers expect. And when you factor in the dramatically lower purchase price of a lab-grown diamond, the financial equation often favors the lab-grown stone.

Let us explore the details.

The Reality of Diamond Resale Value

Most consumers are surprised to learn that diamonds, in general, do not hold their value well. This is true for mined diamonds as well as lab-grown ones.

When you buy a diamond ring at retail, you are paying for more than the stone. You are paying for the brand, the marketing, the rent of the store, the salaries of the staff, and the profit margin of the retailer. These costs can represent fifty to seventy percent of the retail price.

When you try to resell that diamond, you are competing with wholesalers who buy directly from mines and laboratories. You cannot recoup the retail markup. You can only recoup the wholesale value of the stone.

For a mined diamond, a typical resale price is between twenty and fifty percent of the original retail price. A diamond that cost ten thousand dollars at retail might sell for two to five thousand dollars on the secondary market.

For a lab-grown diamond, the resale market is still developing. Currently, resale prices are lower than those for mined diamonds, often in the range of ten to thirty percent of the original retail price.

These numbers may sound discouraging. But they need to be understood in context.

The Purchase Price Changes Everything

Let us compare two scenarios, both realistic.

In the first scenario, you buy a one-carat mined diamond ring for eight thousand dollars. Years later, you decide to sell it. You receive twenty-five percent of the retail price — two thousand dollars. Your net loss is six thousand dollars.

In the second scenario, you buy a one-carat lab-grown diamond ring of identical quality for two thousand dollars. Years later, you decide to sell it. You receive fifteen percent of the retail price — three hundred dollars. Your net loss is seventeen hundred dollars.

In absolute dollars, you lost far more on the mined diamond — six thousand dollars versus seventeen hundred. The mined diamond retained a higher percentage of its value, but because the initial purchase price was so much higher, the absolute loss was greater.

This is the paradox of diamond pricing. A higher resale percentage does not always mean a better financial outcome. The purchase price matters enormously.

Why Do Lab-Grown Diamonds Have Lower Resale Value?

The reasons are economic, not physical. A lab-grown diamond is chemically, physically, and optically identical to a mined diamond. It will not degrade, fade, or lose its brilliance over time. It is eternal.

But the resale market for lab-grown diamonds is still young. The technology to create them is relatively new, and the supply is growing. As production becomes more efficient, the wholesale price of lab-grown diamonds may continue to decline. This affects the resale value of stones purchased today.

The mined diamond industry, by contrast, has had over a century to establish its resale market. The infrastructure of dealers, auction houses, and certification is well established. But even with this infrastructure, the average consumer struggles to recoup a significant portion of their investment.

Are Diamonds an Investment?

The short answer is no. Diamonds are a poor financial investment for the vast majority of consumers.

A financial investment is something you buy with the expectation that it will increase in value over time. Stocks, bonds, real estate — these are investments. They generate income or appreciate in value.

A diamond is a consumer good. It is something you buy to enjoy, to wear, to celebrate a milestone, to symbolize a commitment. It has emotional value, aesthetic value, and sentimental value. But it is not a financial asset.

This is true of almost all luxury goods. A designer handbag, a fine watch, a luxury car — they all lose value the moment you purchase them. The value they provide is in the pleasure of ownership, not in their potential resale price.

We believe this is liberating, not discouraging. When you free yourself from the myth of diamond investment, you can focus on what truly matters: choosing a diamond that is beautiful, meaningful, and aligned with your values.

The Emotional Value of a Diamond

A diamond is not a stock certificate. It is a symbol. It represents a moment — a proposal, an anniversary, a birth, a personal achievement. It carries the weight of memory.

This emotional value does not depreciate. It grows stronger with time. The diamond you chose for your engagement will always be that diamond, regardless of its resale price. The bracelet you bought to celebrate a promotion will always carry that meaning. The earrings you inherited from your mother will always be priceless to you.

When you buy a lab-grown diamond, you are buying that same emotional permanence. You are buying a diamond that will last forever, that will never scratch or fade, that can be passed down through generations. The fact that it cost less to purchase does not diminish its meaning. If anything, it enhances it — because you made a conscious choice aligned with your values.

What About Insurance?

While resale value is limited, insurance value is not. A certified diamond, whether mined or lab-grown, can be insured for its full retail replacement value. If your diamond is lost, stolen, or damaged, your insurance will cover the cost of replacing it with a diamond of comparable quality.

This is a far more practical consideration than resale value. You are far more likely to insure your diamond than to sell it. And insurance companies do not distinguish between mined and lab-grown diamonds. They insure both at their appraised retail value.

At Made of Shine, every diamond comes with a full certificate from GIA or IGI, which you can use to obtain insurance coverage. We recommend insuring your diamond as soon as you receive it.
