A 207.29 carat rough diamond recovered at its Zarnitsa mine in the Yakutia.
The gem quality diamond measuring 38 Ñ… 37 Ñ… 18 millimeters is the largest found since open cast mining started at the Zarnitsa pipe in 1999.
Diamond production in the first quarter at Zarnitsa was 2.3 times the output year on year due to mine capacity.
