A unique rough diamond weighing almost 200 carats has been mined at the Alrosa owned Udachnaya kimberlite pipe in January 2019.
The gemstone, with weight of 191.46 carats, was extracted at processing plant N12 of the Udachny mining and processing division. The diamond is transparent, with a slight yellowish tinge. The Udachnaya pipe was discovered in 1955 and is among the largest primary diamond deposits both in Yakutia, Russia, and abroad.
Evgeny Agureev, member of the management board and director of the United Sales Organization at Alrosa, said: “Such large gem-quality discoveries, weighing more than 100 carats, confirm that there are many unique precious minerals in the reserves of the Udachnaya kimberlite pipe.
“Since the beginning of the development in 1967, the pipe has given hundreds of large diamonds to our company. In the near future, this rare specimen will go to the United Selling Organization for the detailed study and evaluation.”
