The early American synthetic diamond producers, such as GE, mainly focused on producing industrial diamonds for grinding and other applications not requiring gem quality. They were never interested in taking on the DeBeers monopoly with gemstones. AFAIK, some of the earliest gem-quality synthetic diamonds were Russian. The Chinese are important because they can evade DeBeers and its influence over the diamond cutting and distribution establishment. I'm all in favor of synthetic gemstones. Carbon is carbon, mined or not.
