Alrosa has recovered a 98.63 carat diamond from its Jubilee pipe in Yubileynaya, Russia.
The Aikhal Mining and Processing Division (MPD) extracted the stone, which is a transparent yellow-tinted octahedron crystal measuring 28.96 х 28.03 х 27.30 mm.
Evgeny Agureev, director of Alrosa, said: “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.”
