Moscow--Alrosa has recovered another big rough diamond from the Jubilee pipe, the mining company reported Friday.
The company’s Aikhal Mining and Processing Division extracted a 98.63-carat diamond at processing plant No. 14.
The diamond is a described as a “transparent yellow-tinted” octahedron crystal with olivine, graphite and sulphide inclusions. It measures 28.96 x 28.03 x 27.03 mm.
Evgeny Agureev, director of Alrosa’s United Selling Organization (USO), said the company will send the stone to its USO for a detailed examination and valuation.
He said that this latest find, which weighs almost 99 carats, confirms the fact that Jubilee is Alrosa’s best source of big diamonds today. More than 20 rough diamonds weighing more than 50 carats have been extracted from the pipe so far this year.
These include the three diamonds pictured above that were recovered in October and weigh (from left to right) 82.82 carats, 163.11 carats and 108.34 carats.
There was also a 51.91-carat rough diamond found in the fall, dubbed “Russian Ambassador Andrey Karlov,” and in November Jubilee yielded a 68.66-carat diamond that Alrosa named in honor of two-time world champion freestyle wrestler Viktor Lebedev.
The Jubilee pipe was discovered in 1975 and ranks among the world’s primary diamond deposits.
