A rough diamond weighing almost 200 carats was mined at the Udachnaya kimberlite pipe in January, Russian mining giant Alrosa announced recently.
The gem, with dimensions of 40 x 31 x 20 mm and a weight of 191.46 carats, was extracted at a processing plant of the Udachny mining and processing division. The diamond is transparent, with a slight yellowish tinge.
“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,” said Evgeny Agureev, director of the United Sales Organization at Alrosa. “Since 1967, the pipe has given hundreds of large diamonds to our company. This rare specimen will go to the United Selling Organization for evaluation.”
A rough diamond comparable in size to the latest find was unearthed by Alrosa more than two years ago.
