ALROSA Finds Largest Diamond in Zarnitsa's History

30. 5. 2016

ALROSA discovered a 207.29-carat rough diamond at its Zarnitsa mine in the Russian republic of Yakutia.

The gem-quality diamond measuring 38 х 37 х 18 millimeters is the largest found since open-pit mining started at the Zarnitsa pipe in 1999. As yet unnamed, the stone has a “transparent transitional crystal form” and slightly grooved surface.

In the first quarter, diamond production at Zarnitsa was 2.3 times the output from a year ago because of an increase in open-pit mine capacity, ALROSA pointed out.

“The modern mining and processing technologies ensure a high degree of diamond preservation,” said Gleb Shmarov, chief geologist at ALROSA’s Udachny Mining and Processing Division, which discovered the stone.
