A singel 3 carat Yellow diamond takes a couple of days and costs $100. It retails for $10-$15,000. Virtually indistiguishable from "real" diamonds.
It also describes a company making perfect diamonds- not just gemstone quality, we're talking nearly as perfect as a carbon-atom crystal can theoretically form- via vapor deposition. An inch square and builds up at half a millimeter a day. Two months and you could theoretically have a perfect diamond a full inch on a side.
More interestingly, the vapor deposition can be a plating, similar to coating things with Titanium Nitride, which is also a vapor-deposition process.
Now, combine that with a prototype diamond-semiconductor chip that operates at 81 Gigahertz:

Eighty-one Gigahertz. Kind of makes your Pentium 4 at 3.5 Ghz look a little weak? They think that the diamond technology they're working on now, could lead to 200 or 300 Ghz processors.
TeraHz computers are not far off.
Amazing...
