In Yakutia, on the edge of the city of Mirny, is located one of the largest diamond quarries in the world opened in 1955. The quarry has a depth of 525 meters and a diameter of 1.2 kilometers.
It is clearly visible even from space. Kimberlite ore mining was discontinued in June 2001. Currently, an underground mine of the same name is being built on board the quarry, to refine the remaining underground reserves.
Here you can learn everything about diamond mining and buy diamonds at cost price. On December 23, 1980, a large jewelry diamond weighing 342.5 carats was mined at the Mir career.
