Are lab-grown diamonds real diamonds?

Yes. A lab-grown diamond is pure crystallized carbon with the same chemical, physical, and optical properties as a mined diamond. The U.S. FTC recognizes them as diamonds. The only difference is that one was grown in a lab and the other formed underground.

Will a lab-grown diamond pass a diamond tester?

Yes. A standard diamond tester reads a lab-grown stone as a genuine diamond, because it is one. Telling a lab-grown and natural diamond apart requires specialized equipment in a gemological lab.

Why are lab-grown diamonds cheaper?

Lab-grown diamonds can be produced repeatedly in controlled environments. As growing technology improved, supply increased substantially while production costs declined. Natural diamonds require exploration, mining, sorting, and cutting, and their supply is geologically fixed, which keeps prices higher.

How much cheaper are lab-grown diamonds?

As of 2026, a comparable lab-grown diamond typically costs 70-90% less than a natural one at the same size and quality. The gap has stabilized rather than continuing to widen.

Do lab-grown diamonds hold their value?

Not especially. Because they can be reproduced on demand, lab-grown diamonds usually resell for significantly below the original purchase price. Natural diamonds hold value better, but neither type is a sound financial investment once retail markup is accounted for.

Are lab-grown diamonds worth it?

For most buyers focused on maximizing size and quality within a budget, yes: you get identical material at a fraction of the price. They are a weaker choice if resale value, rarity, or mined provenance is the priority.

Does GIA certify lab-grown diamonds?

Yes. GIA issues grading reports for laboratory-grown diamonds as well as natural ones, and the report states the stone's origin. IGI also grades a large share of lab-grown inventory.

Can anyone tell if my diamond is lab-grown?

Not by looking. To the eye they are identical. Only a gemological lab with specialized instruments can distinguish them, and the grading certificate will state which type it is.

Which is better for an engagement ring, lab-grown or natural?

Both are equally durable for everyday wear. Lab-grown gets you more size and sparkle per dollar; natural offers rarity and better value retention. It comes down to budget and what the stone's origin means to you.
