I videoed this on 24 July 2013 during a trip with Alrosa, the company that owns and runs the mine. - Mir Diamond Mine: A kimberlite diamond pipe also called Mirny Mine. The open cut pit is 525 meters (1,722 ft) deep (4th in the world) and has a diameter of 1,200 m (3,900 ft), and is the second largest excavated hole in the world. They now mine underground beneath the pit below 1 km. Some of the facts on the Wikipedia site are outdated and wrong. The mine is still very much active below ground.
