A meteorite impact 35 million years ago in Siberian, is said to have brought enough industrial diamonds which could supply the globe for thousands of years.
The discovery of meteorite crater known as Popigai in the early 1970s contains more industrial quality diamonds than all the present known deposits around the world.
The Diamonds crystal formation makes them much harder than gem quality diamonds, and could make them important in high grade industrial uses.
The meteorite crater is 100 kilometres in diameter was kept secret for close to two decades.
