ALROSA held a media preview of a collection of large coloured polished 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, ALROSA said.
The rough it was cut and polished from was mined in 2017 at the Ebelyakh deposit in Yakutia. The largest pink diamond mined by ALROSA prior to the recovery of this stone was 3.86 carats.
“Pink diamonds along with 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. I am sure that this diamond will be the most expensive in the history of Russia’s gem cutting industry,” said ALROSA Deputy CEO Yury Okoyemov.
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. The diamonds are slated for certification by the Gemological Institute of America (GIA).
The other diamonds displayed in the collection included a pink purple cushion-shaped stone weighing 11.06 carats and recognised by the GIA as the largest of its colour in the world.
Okoyemov commented, “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.”
He added, “According to market analysts, the average price for coloured stones has risen consistently by 12 percent a year over the last few decades. We calculate that the huge potential of its resources will very soon enable ALROSA to become the leader in the international market for coloured diamonds.”
