Russian diamond miner Alrosa has mentioned several times recently that it is aiming to become the leader in the international market for colored diamonds, and is making its case with a media preview of its collection of large colored diamonds, including unique pink, bright yellow and pink purple gems. The star of the show was a pink oval diamond weighing 14.83 carats - the largest pink diamond in the history of Russia.
The rough stone it was cut from, weighing 27.85 carats and “of gem-quality and almost free of inclusions,” was mined in 2017 in the Ebelyakh deposit in Yakutia, Russia and became the largest pink diamond ever to be mined in Russia. In 2017, The National Jeweler rated it as the best discovery of the year (tied with a stunning 34.17-carat vivid yellow diamond also discovered at the Ebelyakh alluvial deposit in Russia). Before it was mined, ALROSA’s largest pink gem had weighed 3.86 carats. “Pink diamonds among the blue ones are considered to be the rarest and most precious of all, and the size and clarity of this specimen makes it one of the best to be discovered anywhere in the world in recent years," said Yury Okoyemov, Deputy CEO of Alrosa. "I am sure that this diamond will be the most expensive in the history of Russia’s gem cutting industry.”
The largest stone in the exhibition was a deep yellow asscher cut diamond, weighing 20.69 carats. It was cut from a raw crystal with a rare honey hue, which weighed 34.17 carats and was the largest yellow diamond mined in Russia in 2017. Pink and yellow diamonds will be soon transferred to GIA (Gemological Institute of America) for certification. Yury Okoyemov added, “The diamonds we are now exhibiting are completely unique, and each of them perfectly embodies the Russian art of gem cutting. And more than half of the several dozen coloured gems we are exhibiting today are large diamonds with fancy hues – the rarest and most beautiful type of diamond. To put it more clearly – out of every ten thousand natural jewellery-class diamonds mined, only one will be coloured, and large coloured diamonds are even rarer. According to market analysts, the average price for coloured stones has risen consistently by 12% a year over the last few decades.”
