Lab Grown Diamonds

Lab-grown diamonds are real diamonds grown in weeks rather than over billions of years, and they have reshaped what an engagement-ring budget can buy. This hub gathers our coverage on how they’re produced (HPHT and CVD), how they stack up against natural diamonds on price, resale and detection, whether they’re genuinely more sustainable, and which retailers sell them well. If you’re weighing size against spend, this is the topic that changes the math.

Ethical & Sustainable

Are Lab-Grown Diamonds Actually Eco-Friendly?

The honest answer depends almost entirely on where the electricity comes from — and the FTC is now cracking down on brands that skip that caveat.

Frequently asked

Are lab-grown diamonds cheaper than natural?

Yes, substantially. A lab-grown diamond typically costs far less than a natural diamond of the same size and quality — often less than half, and the gap has widened as production has scaled. That price difference is the main reason buyers choose lab-grown: it lets them get a noticeably larger or higher-quality stone for the same budget.

Do lab-grown diamonds hold their value?

Lab-grown diamonds have lower resale value than natural diamonds, and their resale prices have fallen as production costs dropped. Both natural and lab-grown diamonds lose value the moment you buy at retail, so neither should be treated as an investment — but if eventual resale matters to you, a natural diamond retains more.

Can a jeweler tell a lab-grown diamond from a natural one?

Not by eye — they are optically and physically identical. Distinguishing them requires specialized laboratory equipment that detects subtle differences in growth structure and trace elements. Reputable lab reports from GIA or IGI clearly state whether a diamond is laboratory-grown, and many lab-grown stones are laser-inscribed to disclose their origin.
