In September, ALROSA recovered a large diamond of 102.85 carats from Jubilee kimberlite pipe. The diamond was extracted by the company’s business unit Aikhal Mining and Processing Division (MPD) at the processing plant No.14.
The diamond has octahedral shape; it is transparent, with moderate yellowish hue. There are small olivine, graphite and sulphide inclusions in this crystal.
According to experts of ALROSA’s Diamond Sorting Center, this stone may be valued at more than $480 thousand if put on auction.
Jubilee pipe is famous for its large finds. Six diamonds from 50 to 120 carats were recovered from the deposit year to date. The fact of extraction of one of them, a 76.07-carat diamond, was named in honor of 70 Years of Victory in the Great Patriotic War – the substantial part of World War II.
