Mir Mine
An unknown photographer captured this image of a Mir mine located in the Siberian tundra with his drone. Mir mine was the first developed diamond mine of the Soviet Union and is the biggest hole ever excavated.
In 1955, a team of Soviet geologists discovered the diamonds for the first time. The Chief Geologist Yuri Khabardin received the Lenin Prize for this amazing discovery. Each year, 10,000,000,000 carats of diamonds were mined at this location.
