'We are speaking about trillions of carats': Russia reveals vast diamond source under 62-MILE-WIDE asteroid crater which could supply world markets for next 3,000 years

Supply under 35million-year-old impact zone is ten times bigger than global reserves

Kremlin discovered the site in the 1970s but kept it a secret until now to exploit tightly controlled market

Diamonds at Popigai Astroblem in Siberia are 'twice as hard' as normal, making them ideal for high-precision scientific instruments and industry



Russia is about to start tapping into a huge source of diamonds that could supply the world market for the next 3,000 years.

Scientists estimate there are 'trillions of carats' lying beneath a 35million-year-old asteroid crater in Siberia - more than ten times the global stockpile.

The Kremlin has known about the reserves under the 62-mile-wide impact zone since the 1970s.

But it has kept it a secret until now because it was already reaping big profits in what back then was a heavily controlled market.

The Soviets had also been producing various artificial diamonds for industry which proved a lucrative enterprise.

Government officials finally gave scientists from the nearby Novosibirsk Institute of Geology and Mineralogy permission to lift the lid on the crater's hidden gems in a meeting with journalists over the weekend.



The official news agency, ITAR-Tass, said the diamonds at the site, known as Popigai Astroblem, are 'twice as hard' as the usual gemstones, making them ideal for industrial and scientific uses.

According to The Christian Science Monitor , the institute's director, Nikolai Pokhilenko, told the agency that the new source would cause a radical shake-up in the precious stones market.

THE MINE THAT MADE RUSSIA £10BN



Russia's lucrative diamond industry was fuelled in large part by the colossal mine at Mirny, above, in Yakutia, which produced immense profits for the country. Operations started in the 1950s when scientists discovered a huge diamond deposit at the site, some 4,300km from Moscow. In the following half century, the mine yielded diamonds worth at least $17bn (£10bn). The pit shut down 11 years ago due to dwindling yields and safety issues. The Russian state diamond company Alrosa later began mining underground, but this is far more expensive and came during the financial meltdown. The new source at Popigai Astroblem makes Mirny look like a mere rabbit hole and will bring a much-needed revival to the industry.



'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,' he said.

'We are speaking about trillions of carats. By comparison, present-day known reserves in Yakutia (a Russian mine) are estimated at one billion carats.'

The stones at Popigai are known as 'impact diamonds' which result when an object like a meteor strikes an existing diamond deposit.

They are also unique, which will make them even more sought-after in high-precision scientific and industrial markets.

Pokhilenko said: 'The value of impact diamonds is added by their unusual abrasive features and large grain size.

'This expands significantly the scope of their industrial use and makes them more valuable for industrial purposes.'

Diamond production was booming in Russia in 2007 when output reached $1.35billion, 98 per cent of which was exported to Belgium, Israel, South-east Asia and the USA.

But the bottom fell out in 2009 when polished diamond production fell to an unprecedented low of US$350 million during the economic crisis.
