ALROSA Extracts 191-Ct Diamond, Largest Found In Recent Years

(IDEX Online) – A rough diamond weighing almost 200 carats was mined at the Udachnaya kimberlite pipe in mid-January 2019, said diamond giant ALROSA.

The gemstone had dimensions of 40x31x20 mm and a weight of 191.46 carats. It was extracted at the processing plant N12 of Udachny mining and processing division. The mined 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, Member of the Management Board, Director of the United Sales Organization at ALROSA. "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 detailed study and evaluation."

A diamond comparable in size was found at the company's deposits more than 2.5 years ago.

The Udachnaya pipe was discovered in 1955, and is among the largest primary diamond deposits both in Yakutia and abroad.
