The Udachnaya pipe (Russian: тру́бка Уда́чная, literally lucky pipe) is a diamond deposit in the Daldyn-Alakit kimberlite field in Sakha Republic, Russia.[1] It is an open-pit mine,[2] and is located just outside the Arctic circle at 66°26′N 112°19′E.[3]

Udachnaya was discovered on 15 June 1955, just two days after the discovery of the diamond pipe Mir by Soviet geologist Vladimir Shchukin and his team.[4] It is more than 600 metres (1,970 ft) deep, making it the third deepest open-pit mine in the world (after Bingham Canyon Mine and Chuquicamata).[4]

The nearby settlement of Udachny is named for the deposit.

As of 2010, Udachnaya pipe is controlled by Russian diamond company Alrosa, which planned to halt open-pit mining in favor of underground mining in 2010.[2]

The mine has estimated reserves of 225.8 million carats (45.16 t) of diamonds and an annual production capacity of 10.4 million carats (2.08 t).[5]
