Russia’s Alrosa, the world’s top diamond producer by output in carats, has unearthed 27.85-carat pink precious rock the company believes could be the most expensive it has ever found.
The miner, majority-owned by the Russian government, said the gem-quality stone was found at its alluvial mines in Russia’s Far East, adding that the largest pink diamond it had previously discovered was less than 4 carats in weight.
Coloured diamonds, especially pink ones, have been lately setting records in auctions. In April, Sotheby’s sold a 59.6-carat one — the ‘‘Pink Star’’ — for $71.2 million. Until then, the most expensive diamond ever sold at auction was the "Oppenheimer Blue," which fetched 56.8 million Swiss francs (more than $57 million at the time) in May 2016.
The previous world auction record for a pink diamond was $46.2 million for the 24.78 carat "Graff Pink" in 2010.
Alrosa noted that it is currently trying to decide on whether to sell this pink rock as a rough diamond, or cut and polish it.
