Two intersecting kimberlite pipes, intruded into Lower Ordovician limestone. The pipes contain diamond eclogite, dunite and peridotite xenoliths and are mined in an open pit more than 600 metres deep.
Discovered in 1955. As of 2010, Udachnaya pipe is controlled by Russian diamond company Alrosa, which planned to halt open-pit mining in favour of underground mining in 2010.

Eclogites are rich in intergranular sulfides (pyrrhotite, pyrite, pentlandite, chalcopyrite, cubanite, djerfisherite) associated with magnetite.
