ALROSA Recovers 191.46-Ct. Rough Diamond At Udachnaya Pipe

ALROSA announced it had recovered a 191.46-carat rough diamond at its Udachnaya kimberlite pipe. The stone is transparent, with a slight yellowish tinge.

ALROSA United Sales Organisation (USO) Director Evgeny Agureev commented, “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 detailed study and evaluation.”

A rough diamond comparable in size was found at the company's deposits more than 2.5 years ago. The Udachnaya pipe was discovered in 1955. It is among the largest known primary diamond deposits.
