Russia’s Alrosa has unearthed a pink diamond that the gem giant says could be the most expensive it has ever found.

Alrosa, which produces more stones than anyone else, found the 27.85 ct pink gem at its alluvial mines in Russia’s Far East. The company said the biggest pink diamond it had previously found was less than 4 ct in weight.
