1 min read
Quick answer: Lab-grown diamond = chemically identical to natural diamond, 70–80% cheaper. No mining, IGI certifiable – a real diamond from the lab.

A lab-grown diamond (laboratory diamond) is a diamond that is produced in a laboratory under the same physical conditions as natural diamonds – chemically, physically, and optically identical to a natural diamond. It costs 70–80% less.

Lab Grown vs. Natural Diamond

  • Chemistry: Identical – pure carbon in cubic crystal structure
  • Hardness: Identical – Mohs 10
  • Brilliance: Identical
  • Price: Lab-grown 70–80% cheaper
  • Resale: Lab-grown has no stable secondhand market
  • Origin: No mining – no ethical complications

Does a lab-grown diamond need a certificate?

Yes – IGI (International Gemological Institute) certifies lab-grown diamonds with the same 4Cs as GIA certifies natural diamonds. Without a certificate, there is no proof of quality or laboratory origin.
