Looks like one of my least favorite monopolies, De Beers, is going to have some competition in the form of cheap, gem quality, man made diamonds. How does a 3 carat yellow diamond sound? It goes for about 15 grand in Amsterdam. How about for a hundred bucks? Or a carat worth of raw material for a diamond-based semi-conductor capable of running at 81 GHz? 5 bucks. Of course, carbon and carbon-based molecules are also great in more messy, finished forms like turkey offal, old fridges, tires - you know anything that can be turned into oil.
