The Mir mine (Russian: Ми́р, IPA: [ˈmʲir]; lit. 'Peace'), also called the Mirny mine, is an open pit diamond mine located in Mirny, Sakha Republic, in the Siberian region of eastern Russia. It was the Soviet Union's first developed diamond mine, and became its largest after open-pit mining began in 1957. The pit is more than 525 meters (1,722 ft) deep (4th in the world), has a diameter of 1,200 m (3,900 ft), and is one of the largest excavated holes in the world.
Both of the two then-largest diamonds mined in Russia were discovered at Mir, in 1980 (weighing 342.57 carats) and 2025 (weighing 468 carats). The mine's surface operations were discontinued in 2001, but in 2009 it became active again as an underground diamond mine.
