What is a lab-grown diamond?
Kurz gesagt:
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.
