September 18, 2012 - Russia
has just declassified news that will shake world gem markets to their core: the ," enoudiscovery of a vast new diamond field containing "trillions
of carats" enough to supply global markets for another 3,000 years. The Soviets discovered the bonanza back in the 1970s beneath a 35-million-year-old, 62-mile diameter asteroid crater in eastern Siberia
known as Popigai Astroblem.
They decided to keep it secret, and not to exploit it, apparently because the USSR's huge diamond operations at Mirny, in Yakutia, were already producing immense profits in what was then a tightly controlled world market.

The Soviets were also producing a range of artificial diamonds for industry, into which they had invested heavily.
The veil of secrecy was finally lifted over the weekend, and Moscow
permitted scientists from the nearby Novosibirsk Institute of Geology and Mineralogy to talk about it with Russian journalists.
According to the official news agency, ITAR-Tass, the diamonds at Popigai are "twice as hard" as the usual gemstones, making them ideal for industrial and scientific uses.
The institute's director, Nikolai Pokhilenko, told the agency that news of what's in the new field could be enough to "overturn" global diamond markets.
"The resources of super-hard diamonds contained in rocks of the Popigai crypto-explosion structure, are by a factor of ten bigger than the world's all known reserves," Mr. Pokhilenko said. "We are speaking about trillions of carats. By comparison, present-day known reserves in Yakutia are estimated at one billion carats."
The type of stones at Popigai are known as "impact diamonds," which theoretically result when something like a meteor plows into a graphite deposit at high velocity. The Russians
say most such diamonds found in the past have been "space diamonds" of extraterrestrial origin found in meteor craters.
