Alrosa Make Large Diamond Find


Diamond mining company Alrosa have found a 102.85 carat diamond in their Jubilee kimberlite pipe in Siberia, Russia. One of the largest diamond mines in the world, it has estimated reserves of more than 170 million carats, and has a solid reputation for large diamond finds.

This recent find was made in September and is of classic octahedral shape. Resembling two back-to-back pyramids, the octahedron is the most commonly found shape for rough gem diamonds. Alrosa have announced that the stone is transparent with a moderate yellowish hue and has small inclusions of olivine, graphite and sulphide. Experts have estimated its value at around $480,000 (£312,400).
