Russian diamond producer Alrosa assembled a preview of its collection of large coloured diamonds, including pink, bright yellow, and purple-pink gems.
Among the displayed pieces was a pink oval diamond weighing 14.83 carats—the largest of its kind to be discovered in Russia.
“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, the company’s deputy CEO.
The pink diamond was cut from a gem mined in the Ebelyakh deposit in Yakutia, Russia, in 2017. Before its discovery, the largest pink gem discovered by Alrosa had weighed 3.86 carats.
Also on display was a 20.69-carat deep yellow diamond, which was cut from a raw crystal with a honey hue weighing 34.17 carats, and a purple-pink cushion-cut stone weighing 11.06 carats, which has been recognized by the Gemological Institute of America (GIA) as the largest of its colour to ever be certified.
“The diamonds we are now exhibiting are completely unique, and each of them perfectly embodies the Russian art of gem cutting,” said Okoyemov. “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.”
