Russian mining giant Alrosa has recovered a large gem-quality diamond of 98.63 carats from its Jubilee pipe at the Aikhal Mining and Processing Division.
The diamond, according to Alrosa, is a “transparent yellow-tinted octahedron crystal with inclusions of olivine, graphite and sulphide”, measuring 28.96 х 28.03 х 27.30 mm.
Director of Alrosa’s United Selling Organization (USO), Evgeny Agureev, stated: “One more discovery weighing almost 100 carats confirms the fact that Jubilee pipe today is ALROSA’s absolute leader in the recovery of large gem-quality diamonds. According to our information, more than 20 large rough diamonds over 50 carats have been extracted from Jubilee since the beginning of 2017. We are waiting a new stone to be delivered to USO for a detailed examination and valuation”.
In mid-November, Alrosa recovered three large gems from Jubilee. The diamonds include a 82.82-carat octahedron rough, a transparent yellow-tinted crystal with small inclusions; a 108.34-carat rough diamond rough, a transparent yellow-tinted crystal with small inclusions; and a 163.11-carat rough, a transparent yellow-hue crystal with inclusions near the surface.
