A bit off topic but I thought you might enjoy it. This is the Mirny Mine in the Sakha Region of Siberia, Russia. This diamond mine, one of deepest excavated holes on earth is 1,755 ft (525 m) deep and 3,900 ft (1,200m) across. Opened in 1957, at its height it was producing 10,000,000 carats a year. It closed operations in 2004. Below the city of Mirny was built right up the edge of the open pit mine. The diamonds were both jewelry and commercial grade stones used in optics, communication, diamond coating as well as commercial and medical lasers.
