Mining News - The diamond is the largest fancy-coloured precious gemstone ever extracted by Almazy Anabara, Alrosa said. It measures 20.17 by 19.65 by 15.1 mm and is a transparent intense yellow crystal with a small inclusion in the intermediate zone.

Alrosa has hit this year a record in the number of large fancy-coloured diamond found at its operations.

“We used to extract fancy-coloured rough diamonds over 10 carats once a year on the average, but this year we have already recovered several large fancy-coloured diamonds,” the company said in the statement.

In June, Alrosa unearthed a 65.75-carat yellow diamond at its prolific Jubilee pie and, in September, it recovered a unique 27.85-carat pure pink diamond — the largest of its kind Alrosa has ever found.

The company’s plan is to send the newly found diamond to the United Selling Organization Alrosa (USO Alrosa) in Moscow, where specialists will give it a more detailed and accurate assessment, before the end of October.
