Two American companies have developed two different methods of making diamonds that could be considered technically "real" because they are made using compressed carbon, just as nature's diamonds are. Diamonds made this way will enable the eventual development of semiconductors that can take immense amounts of heat, but through the development, the companies have found that their diamonds are as beautiful and more flawless than those from the mines, and they can be made for a fraction of the cost of mined diamonds. Apparently, this is causing diamond company De Beers a great deal of frustration, and even scaring them silly:
Quote:According to Clarke, a De Beers executive, James Evans Lombe, was tipped off about the synthetic diamonds within two hours of their arrival at the jeweler's. Lombe asked for a meeting with the General. The De Beers executive drove directly to Claridge's, and the two men sat down in the tearoom to the strains of a piano and violin duet.
De Beers refuses to comment on the meeting - or about anything for this story - but Clarke says he simply placed his diamonds on the table. "When I told him that we planned to set up a factory to mass-produce these, he turned white," the General recalls. "They knew about the technology, but they thought it would stay in Russia and that nobody would get it working right. By the end of the conversation, his hands were shaking."
De Beers has begun a campaign against "manufactured diamonds" and has developed their own machinery that will detect natural vs "cultured" (as one diamond maker likes to call it), but even their detection machinery has a hard time telling the difference.

Would it make a difference to you if a diamond was manufactured by machine rather than by earth if it were still flawless and still technically a real diamond?
