Alrosa Unearths Giant 214.65-carat Diamond
The 214.65-carat rough Diamond was recovered from the Nyurbinskoye placer deposit. Udachny open-pit mine consists of 2 pipes and it is famous for yielding massive Diamonds.
Russia’s Alrosa (MCX:ALRS), the world’s #1 Diamond producer by output in carats, said last week it has recovered a 214.65-carat rough stone from its Nyurbinskoye placer deposit.
The crystal measures 42.11 by 34.26 by 16.07 mm, and is translucent with a grey hue, Alrosa said.
Traces of dissolution, tetragonal cavities, etching channels and caverns, are observed on the surface.
The Nyurbinskoye deposit is located close to the Nyurbinskaya pipe primary deposit, a known source of big stones, which is run by the Nyurba Mining and Processing Division, one of Alrosa’s youngest units.
Last week Russia’s government completed the sale of a 10.9% stake in the miner. It was the biggest divestment of a state asset since the government reduced its stake in the Diamond producer almost 3 years ago.
