article imagePossibly world's richest diamond field found in asteroid crater

By Greta McClain     Sep 19, 2012 in World
Recently declassified Russian documents show the existence of what may be the world's richest diamond field located in a 62-mile diameter asteroid crater known as Popigai Astroblem in Siberia.
These diamonds, known as "impact diamonds", are created when a meteor strikes a graphite deposit, which is what scientists believed happened at Popigai Astroblem approximately 35 million years ago. Impact diamonds are significantly harder than normal diamonds, and are best suited for industrial or scientific use.

According to Yahoo News, Russia discovered the diamonds in the 1970's. They decided to keep it secret however because they had huge diamond operations at Mirny in Yakutia which was already producing immense profits in what was then a tightly controlled world market. The secret was reveled this past weekend when Moscow permitted scientists from the nearby Novosibirsk Institute of Geology and Mineralogy to discuss the find with Russian journalists.
Sky News says the institute is planning to send an expedition to the crater in co-operation with Russia's state-controlled diamond mining company Alrosa.
The Russian Academy of Sciences says that trillions of carats of diamonds are known to be at the crater and the diamonds are "twice as hard" as normal diamonds. The Huffington Post reports Nikolai Pokhilenko, head ot the Geological and Mineralogical Institute in Novosibirsk, as saying the reserve could spark a "revolution" in diamond production.
