Do Lab Grown Diamonds Hold Their Value? Resale Explained

Quick answer: No, lab grown diamonds do not hold their value well. Their resale value is low, and retail prices have fallen sharply over the past few years as production has grown. That does not make them a bad purchase. It means you should buy a lab grown diamond for its beauty, durability and price, not as an investment.

This guide explains why lab diamond resale is low, how that compares with mined diamonds, and how to make a smart choice anyway.

Why Lab Grown Diamonds Have Low Resale Value

Supply is not limited

Mined diamonds depend on what can be found and dug up. Lab grown diamonds can be produced whenever there is demand, so there is no scarcity to support a high resale price.

Prices keep falling

As growing technology improves and more factories open, the cost of making a lab diamond drops. A stone bought a few years ago may now sell new for much less, which pulls down what a buyer will pay for a used one.

Few buyers for used stones

Many jewelers and pawn shops will not buy lab grown diamonds, or they offer very little. When a new certified stone is affordable, most shoppers simply buy new.

Lab Grown vs Mined Diamond Value

It is worth knowing that mined diamonds are not a reliable investment either. Most people who sell a mined diamond get back far less than they paid at retail.

What Actually Sets the Resale Price of a Used Diamond

When you sell any diamond, you are not selling it to a shopper paying retail. You are selling it to someone who has to resell it for a profit, so the offer starts from what that buyer can get for it, minus their margin. For lab grown stones, that starting point is the price of a comparable new stone today, not the price you paid.

The current price of a new equivalent

A buyer will compare your stone with a new lab diamond of the same carat, color, clarity and cut. If the new one is cheaper than your purchase price was, your stone is worth less than you paid before any margin comes off. This is the single biggest factor in lab diamond resale.

Grading report and documentation

A stone with an IGI or GIA report that matches its laser inscription is easier to sell because the buyer does not have to pay for testing and grading. A stone with no paperwork may get a lower offer or no offer, since the buyer is taking on more risk.

Condition

Diamond is the hardest natural material at 10 on the Mohs scale, but it can still chip at a thin girdle or a pointed tip, especially on pear, marquise and princess shapes. A chip lowers value because the stone may need recutting. Wear on the metal setting matters less, since many buyers only want the loose stone.

Size and shape demand

Popular shapes such as round and oval are easier to move than unusual cuts. Very small stones rarely have meaningful resale value at all, because the cost of removing, checking and reselling them can be more than they are worth.

Where You Could Sell a Lab Grown Diamond, and What to Expect

If you ever do decide to sell, it helps to know the options in advance. None of them will return what you paid at retail, but some are more realistic than others.

Retail Price, Appraisal Value and Resale Value Are Three Different Numbers

Shoppers often mix these up, which leads to disappointment later. Each one answers a different question.

• Retail price is what you pay a jeweler for a finished piece. It includes the stone, the metal, the labor and the seller's costs.
• Appraisal value is usually an insurance replacement figure: what it would cost to replace the item new at retail. It is not an offer to buy, and no one is obliged to pay you that amount.
• Resale value is what a buyer will actually pay you in cash. For lab grown diamonds it sits well below both of the other numbers.

Because new lab diamond prices have fallen, replacement cost has fallen too. That is one reason to have the piece re-appraised every few years: you may be paying insurance premiums on a value higher than the actual cost to replace it. Our guide on whether to insure a lab grown diamond ring covers this in more detail.

So Is a Lab Grown Diamond Worth Buying?

For most people, yes, as long as you buy it for the right reasons. The money you save up front is real, and often larger than any resale value a mined diamond would give back. You can put that savings toward a bigger stone, a better cut, an 18K gold setting, or something else entirely.

Lab grown diamonds make the most sense if you plan to keep and wear the piece, which is how most engagement rings and fine jewelry are used.

Lab Diamond vs Mined Diamond vs Moissanite: Value Over Time

If long-term value is on your mind, it helps to compare the three most common center stones side by side. All three are durable enough for daily wear, but they behave differently as purchases.

The honest takeaway: none of these is a savings account. The question is how much you want to spend up front for something you plan to keep. You can compare the stones in more depth on our moissanite vs lab grown diamond vs diamond page, or browse moissanite engagement rings if the lowest upfront cost is your priority.

The Part of a Ring That Does Keep Some Value: The Metal

While a lab diamond has little resale value, the gold in its setting is a commodity with a market price. A gold ring can always be sold for its metal content, although scrap buyers pay less than the full market rate and nothing for the craftsmanship.

This should not drive your choice on its own, since metal prices move up and down too. But if you like the idea that part of the piece holds tangible value, a heavier gold setting is the component that does it, not the stone.

How to Get the Most Ring for Your Money

Since you are buying for wear and not resale, the smart move is to put your budget where your eye will notice it. These choices affect what you see every day far more than what a buyer would pay later.

Prioritize cut

Cut quality decides how bright a diamond looks. A well-cut stone with a slightly lower color or clarity grade will usually look better than a poorly cut stone with top grades on paper.

Choose "eye clean" over flawless

Clarity grades such as VS1 and VS2 typically look clean to the naked eye. Paying for higher clarity buys you a better certificate, not a visibly different stone.

Consider shapes that look larger

Elongated shapes such as oval, pear and marquise spread their weight across a longer surface, so they can look bigger than a round of the same carat weight.

Match the setting to your life

A simple lab diamond solitaire ring keeps the focus on the stone and is easy to maintain, while halos and pavé add sparkle but have more small stones to check. See our full range of lab diamond engagement rings for setting ideas.

How to Protect the Value You Do Have

• Keep the IGI report. A certificate that matches the stone makes any future sale or appraisal easier.
• Insure the ring. Loss or theft is a bigger financial risk than resale value. Ask your insurer about a jewelry rider or a standalone policy.
• Look after it. Regular cleaning and a yearly prong check keep the stone secure and sparkling.
• Ask about upgrades. Some jewelers offer trade-in or upgrade options. Ask before you buy what is available.

Does Color Change Anything?

Fancy color lab grown diamonds, like vivid pink, blue or green, are far more affordable than natural colored diamonds, which can be extremely rare and expensive. The same rule applies: they are a beautiful way to own a bold color, not an investment. Choose the color you love.

Mistakes to Avoid if Value Matters to You

• Buying a lab diamond as an investment. If you expect to sell it for a profit, or even for what you paid, you will almost certainly be disappointed.
• Treating an appraisal as a guaranteed sale price. An appraisal is a replacement estimate for insurance, not a promise of cash.
• Overpaying for grades you cannot see. Top color and clarity grades cost more but rarely change how the stone looks on your hand.
• Losing the paperwork. Keep the grading report, receipt and any appraisal together in a safe place, with digital copies.
• Skipping insurance. Losing a stone outright costs you far more than any drop in market value.
• Assuming every jeweler will buy it back. Many will not buy lab grown stones at all. If a trade-in matters to you, confirm the terms in writing before you buy.

A Value-Smart Buying Checklist

1. Decide whether you are buying to wear, to keep for years, or to sell later. Lab grown diamonds fit the first two.
2. Set a total budget that includes the setting, not only the stone.
3. Choose your shape and setting style first, then look at stones that suit them.
4. Put cut quality first, then pick an eye-clean clarity and a color you are happy with.
5. Ask for the grading report and check that the report number matches any laser inscription.
6. Pick a metal that suits your lifestyle: 10K or 14K for hard daily wear, 18K for richer color.
7. Confirm your ring size with our ring size chart, since everything is made to order.
8. Arrange insurance as soon as the ring arrives, and store your documents safely.

Who a Lab Grown Diamond Suits, and Who It Might Not

A good fit if you want a real diamond for an engagement ring, wedding band or everyday jewelry, you plan to keep it, and you would rather spend the difference on a larger stone, better cut, nicer setting or something else in your life.

Maybe not the best fit if the rarity of an earth-formed stone is important to you, if you expect to sell or trade the piece within a few years and want the highest possible return, or if your partner has a strong preference for a mined diamond. In those cases, talk it through before you buy.

Frequently Asked Questions

Can I sell my lab grown diamond later?

You can, but expect a low offer, and some buyers will not purchase lab grown stones at all. Plan to keep and enjoy it.

Will lab grown diamond prices keep dropping?

Nobody can promise where prices will go. They have fallen a lot in recent years, and many in the industry expect lab grown prices to stay low compared with mined diamonds.

Are mined diamonds a good investment?

Usually not for consumers. Most mined diamonds resell for well below their retail price.

Does a lab diamond lose its sparkle over time?

No. Its physical value, the sparkle and hardness, stays the same for a lifetime. Only the market price changes.

Do lab grown diamonds ever go up in value?

There is no reason to expect that. Production is not limited the way mining is, and prices have generally moved down. Buy one because you want to wear it.

Is an appraisal still worth getting for a lab grown diamond?

Yes, if you plan to insure it. Insurers often want a recent appraisal to set coverage, and it documents the stone's details in case it is lost or stolen.

Will insurance pay back what I originally spent?

It depends on your policy. Many policies replace the item with one of like kind and quality, so if lab diamond prices have fallen, the replacement may cost the insurer less than your original price. Read the terms and ask your insurer.

Does moissanite hold value better than a lab diamond?

No. Moissanite has very little resale value. Its advantage is a low upfront cost and strong fire, not long-term value.

Is the gold setting worth anything if I sell?

Yes, gold can always be sold for its metal content, though buyers pay less than the full market price. A sterling silver setting has much lower metal value.

Can I trade a lab grown diamond toward a mined diamond?

Some jewelers allow it, many do not. Programs differ a lot, so ask the specific jeweler for their written terms before you count on it.

The Bottom Line

Lab grown diamonds do not hold their resale value, and they were never meant to be investments. They are real diamonds that let you get more beauty for your money. Buy the stone you love, keep its certificate, insure it, and wear it every day.
