Russian Asteroid Crater Contains Trillions of Carats Worth of Diamonds Say Russians

Posted on September 18, 2012

The Christian Science Monitor reports that Russia recently declassified news that it has an asteroid crater with trillions of carats worth of diamonds in it. These diamonds are apparently enough to supply global markets for the next 3,000 years. The Monitor syas the crater was discovered in the 1970s in the Popigai asteroid crater.

The type of diamonds in the crater are known as impact diamonds. Gizmodo notes that these diamonds are not useful for jewelry, but very useful in the tech industry, such as in making lasers. They are formed when a meteor or comet strikes Earth and carbon is fused into diamond. However, they have never been found on such a large scale. Richard April, a professor of geology at Colgate University, explains how the formation is possible in a Smithsonian article. However, he says a meteorite-impact crater with this many diamonds in it is unlikely.

A 2004 Geology report on the Popigai crater (which mentions impact diamonds) can be found here.
