CPU's Could be Made From Diamonds in the Near Future

In 2003 it was found that diamonds could be man-made and the processes would produce chemically pure diamonds costing around $100 to produce.  Now days we know how to make these into microchips.  As diamonds can withstand large amounts of heat without effect, have semi-conductive properties, and using another man-made material called graphene with the synthetic diamonds may produce chips with processor speeds that could clock up to and beyond 1,000GHz, they may be the next big break-through in Moore's Law.  De Beers even set up shop in Silicone Valley.  They don't want to miss out on the action, or their piece of the pie.
