ALROSA unearths largest colored diamond found in Russia


Almazy Anabara (Diamonds of Anabar), a part of ALROSA Group, found a 236-ct rough diamond of intense yellow-brown color. The diamond was extracted from the Ebelyakh mine in Yakutia, Russia. This is the largest natural color rough diamond ever found in Russia.

The diamond’s dimensions are 47x24x22 mm, and, according to preliminary estimates, it is 120-230 million years old.

“Such a large natural color rough diamond is a unique discovery. Now the stone is at ALROSA’s United Selling Organization being studied and evaluated by our specialists. After that, we will decide whether to give it to our manufacturers for cutting or sell as a rough. Of course, cutters in any country will be interested in such a diamond, as it has the potential to give several high quality polished diamonds,” said Pavel Vinikhin, head of Diamonds of ALROSA’s cutting and polishing division.

The Ebelyakh alluvial diamond deposit (operated by Almazy Anabara, a subsidiary of ALROSA) is located on the Anabar River of the Republic of Sakha (Yakutia). Previously, several unique fancy color diamonds were unearthed there. In the summer of 2017, ALROSA mined three unique fancy color diamonds within a month: intense yellow, pink and purple-pink. All three stones were cut by the Diamonds of ALROSA division and presented as polished diamonds to the public. At the end of last year, a yellow diamond called Firebird weighing 20.69 carats was sold to Graff Diamonds.
