Reading this thread got me interested in finding some information on the De Beers company and man-made diamonds. I found this very interesting six page article that chronicles some of the battles that are being fought between De Beers and two high tech companies that are manufactoring diamonds. The last part that talks about the technology behind Apollo Diamonds and the examination of their diamonds by a diamond expert who sides with De Beers is amazing.
