Synthetic Ethics

Synthetic diamonds are a fundamental threat to the natural diamond industry. They are not just a competitive product like gems, pearls, or gold jewelry. They are a replacement product. Their marketers shout out: Don’t buy natural diamonds, buy synthetic diamonds because synthetic diamonds are more ethical. They are cheaper. They build up synthetic diamonds by tearing down natural diamonds.

A Diamond is a Diamond?

Retired Brigadier General Carter Clarke, 77, founded The Gemesis Corporation in 1995. The company, based in Sarasota, Florida, is the first to commercially produce gem-quality synthetic diamonds grown using the High Pressure- High Temperature (HPHT) process. Martin Rapaport interviewed Clarke to get an insider view on this new facet of our industry.

Cultured Diamonds

Are laboratory-grown diamonds a threat to the integrity of the diamond industry? Should jewelers support the development of a market for these diamonds? Is it fair to describe these stones as cultured diamonds? What are these stones?

Raining Diamonds

Bryant Linares, president of Apollo Diamonds, a super-high-tech company based in Boston, is interviewed by Martin Rapaport. Apollo produces perfect industrial diamonds using cutting-edge Chemical Vapor Deposition (CVD) technology and plans to enter the gem diamond business in the very near future.


I remember the old days, before certificates, price sheets, fax machines and the internet. I was an apprentice cleaver learning to sort diamonds in the office of Feival Doppelt, one of the great diamond men of Antwerp. Feival liked me and I was lucky to get an opportunity to work at one corner of his massive desk.
