Russia recently revealed that it has a hidden diamond field containing "trillions of carats," which would be enough to supply global markets for 3,000 years.
Apparently, the jewels were discovered in the 1970s beneath a 35-million-year-old, 62-mile diameter asteroid crater in Popigai, Siberia, reports CSMonitor.
The former Soviet Union decided to keep it secret because their real diamond and artificial diamond manufacturing units in Yakutia, Russia were producing huge profits.
The "impact diamonds" are reportedly "twice as hard" as the usual gems and could be used in industrial and commercial projects.
Over the weekend, the Russian government allowed scientists from the Novosibirsk Institute of Geology and Mineralogy to talk about it with journalists.
Novosibirsk Institute of Geology and Mineralogy director Nikolai Pokhilenko said: "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. We are speaking about trillions of carats. By comparison, present-day known reserves in Yakutia are estimated at one billion carats."
Russian scientists say the news is likely to change the shape of global diamond markets.
