Alrosa Recovers Unique Pink 27.85-ct Diamond
Almazy Anabara, a subsidiary of Alrosa, recovered a large pink rough diamond weighing 27.85 carats. The company’s previous largest pink rough diamond weighed about 4 carats. If the company decides to cut this stone, it could become the most expensive polished diamond in the history of Alrosa.
The rough diamond has dimensions of 22.47 x 15.69 x 10.9 mm. The pink stone is of gem-quality and almost free of inclusions.
Alrosa often recovers pink and other coloured diamonds at Severalmaz kimberlite pipes or placer deposits of Almazy Anabara. Coloured diamonds weighing over 10 carats are extremely rare and recovered about once a year. As for the pink shades, by far the largest pink diamond of Alrosa weighed 3.86 carats, found by Almazy Anabara in 2012. Apart from this stone, for the last eight years, Alrosa recovered only three pink diamonds weighing over 2 carats.
“The unique characteristics of the diamond make it an extraordinary, rare stone of high value. Currently, experts of United Selling Organization (USO) Alrosa and the company’s polishing division Diamonds Alrosa are examining the stone to make the decision: whether to auction it as a rough or cut it into a polished diamond. Large stones, especially coloured, are always in demand at auctions. But if the company decided to cut it, it would become the most expensive diamond in the entire history of Alrosa,” said Evgeny Agureev, the head of USO Alrosa.
