Most often ALROSA recovers pink and other colored diamonds at Severalmaz kimberlite pipes or placer deposits of "Almazy Anabara". Colored 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 ct - it was found by "Almazy Anabara" in 2012. Apart from this stone, for the last 8 years ALROSA recovered only 3 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 of 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 polished diamond. Large stones, especially colored, 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.
