Resale Value of Lab-Grown Diamonds: Key Market Insights

Discover the truth about the resale value of lab-grown diamonds and how they compare to natural stones. Get key market insights to make an informed buying or selling decision.

Thinking about selling your lab-grown diamond? Here’s the reality—while these diamonds offer the same sparkle as natural diamonds, their resale value isn’t always what buyers expect.

In fact, research from the Gemological Institute of America (GIA) shows that lab-grown diamonds lose up to 50-70% of their original price on the resale market. That’s a big drop compared to mined diamonds, which generally hold value better.

So, should you buy lab-grown diamonds if resale matters to you? What affects their worth? Let's find out together.

Do Lab-Grown Diamonds Hold Their Value?

Many people wonder if lab-grown diamonds keep their resale value. The short answer? Not as well as natural diamonds.

When you buy lab-grown diamonds, they often cost 30-50% less than mined diamonds. That sounds like a great deal, right? But here’s the catch—when you try to sell lab-grown diamonds, they usually lose value fast. Unlike a natural diamond ring, which holds some of its original price, lab-created diamonds often resell for much less.

Diamonds Have Resale Value

Not all diamonds have resale value in the same way. Mined diamonds are rare because they come from deep inside the earth's crust under extreme pressure conditions. This makes them more valuable in the resale market.

On the other hand, lab-grown diamonds are created in a lab using chemical vapor deposition. Since companies can make an unlimited supply, their market price keeps dropping. That’s why grown diamonds don’t hold their value as well.

Why Some See Lab-Created Diamonds as an Affordable Alternative

Buying a diamond can be expensive. But many people are now choosing lab-grown diamonds instead of natural diamonds. Why? Because they cost 30-50% less and look exactly the same.

Lower Cost, Same Sparkle

A lab-created diamond is made in a lab using chemical vapor deposition or high pressure conditions. This process recreates how diamonds form in the earth’s crust but in a shorter time. The result? A diamond with the same sparkle and quality as mined diamonds but for a much lower price.

More Affordable for Jewelry Buyers

If you’re shopping for an engagement ring, a lab-grown diamond lets you get a larger diamond for the same budget. Many people see this as a smart investment because they can buy a high-quality stone without spending too much money.

While they are affordable, lab diamonds do not hold their resale value as well as natural diamonds. The resale market is still growing, and not all jewelry stores will buy lab-grown diamonds back. If you plan to sell lab-grown diamonds, make sure you check the retail options first.

Understanding the Resale Market for Lab Created Diamonds

Unlike mined diamonds, which come from deep inside the earth’s crust under extreme pressure conditions, lab-created diamonds are made in labs using chemical vapor deposition. This means they can be produced in large numbers, which lowers their market price over time. More supply = lower resale market demand.

Stores that sell lab-grown diamonds rarely offer buyback programs. This makes it hard to find buyers willing to pay a high price for a used lab diamond.

Why Resale Value Matters when Buying Lab Diamonds

If you plan to buy lab-grown diamonds, resale value should be a key factor. Here’s why:

• Lab diamonds lose value faster. A natural diamond ring may keep up to 50% of its original price, while a lab diamond often drops to a fraction of its cost.

• Fewer buyers in the second-hand market. Many people prefer to buy certified diamonds new rather than used.

• Resale options are limited. Unlike natural diamonds, which can be resold at jewelry stores, pawn shops, or online marketplaces, lab-created diamonds have fewer resale channels.

While diamonds dominate the market, other valuable gemstones like sapphires and rubies also hold investment potential.

How Market Price Trends Affect Lab-Created Diamond Worth

1. Increasing Supply Lowers Prices

More people are buying lab-grown diamonds, and manufacturers are producing them faster. Since they are made in a lab using chemical vapor deposition, the supply keeps growing. When there are too many diamonds in the market, their resale value drops. Most lab-grown diamonds resell for significantly less than their original purchase price, making them a less favorable investment.

2. Changing Consumer Preferences Impact Value

Trends in the jewelry industry shift over time. Some buyers prefer natural diamonds because they come from the earth’s crust under extreme pressure conditions. Others like lab-created diamonds because they are more affordable and ethical. If fewer people want lab diamonds, their resale market weakens.

3. Natural Diamond Prices Influence Lab-Grown Worth

The price of natural diamonds affects how much people will pay for lab-grown diamonds. If the price of mined diamonds drops, lab diamonds also become less valuable.

4. Market Competition Reduces Long-Term Value

Many companies sell lab-grown diamonds today. This increases competition, which lowers resale value. If one brand offers cheaper lab diamonds, other companies must adjust their prices too.

5. Retailer Buyback Policies Shape Resale Value

Most retail stores offer buyback programs for natural diamond rings. However, many stores do not accept lab-grown diamonds for resale. This makes selling them harder.

6. Brand Reputation Affects Price Stability

Some brands have a strong reputation, which helps their lab-grown diamonds hold value. Certified lab diamonds from well-known brands sell for more than unbranded ones.

Will Lab Diamonds Hold Value Better in the Future?

The resale value of lab-grown diamonds is a big question for many buyers. Right now, they don’t hold value like natural diamonds. But will that change? Some experts believe lab diamonds could keep more value in the future. As consumer demand grows and more jewelers buy lab-grown diamonds, the resale market might improve.

Diamond Tester: How to Verify a Lab Grown Diamond’s Authenticity

Not sure if your diamond is lab-grown or natural? A diamond tester can help! These devices check if a diamond is real by testing how it reacts to heat and electricity.

1. Can a Diamond Tester Identify Lab-Grown Diamonds?

Yes, but not always! Standard diamond testers detect if a stone is a real diamond, but they can’t always tell if it’s lab-grown or mined from the earth’s crust. A diamond test can help verify whether a stone is lab-grown or mined, you’ll need an advanced tester that checks for chemical vapor deposition signs.

2. The Best Ways to Check Authenticity

• Use a Certified Tester: Some testers can tell the difference between natural diamonds and lab-grown diamonds by analyzing their structure.

• Look for Certification: Trusted labs like the Gemological Institute provide reports confirming if a diamond is lab-created.

• UV Light Test: Some lab-grown diamonds glow under UV light due to their growth process.

3. Does a Lab-Grown Diamond Pass the Test?

Yes! Lab-grown diamonds pass most standard diamond testers because they have the same properties as natural diamonds. But to check if it’s lab-grown, you’ll need a special tester or a certification.
