Russian mining giant Alrosa has recovered three large rough stones from the Jubilee (Yubileynaya) pipe at Aikhal Mining and Processing Division in October.
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.
Director of the USO (United Selling Organization) ALROSA Evgeny Agureev said: “Simultaneous extraction of three large rough diamonds, two of which are over 100 carats, within such a short period of time is a one-off event especially when it comes to gem-quality diamonds. As a rule, only 5-10 similar stones over 100 carats may be recovered within a year, and they are always in great demand at auctions. In the short term, rough diamonds will be delivered to the United Selling Organization (USO) ALROSA, where our experts will give them a detailed assessment”.
