RAPAPORT... 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.
