Russia’s Alrosa the world’s top diamond producer by output in carats, has put together a collection of recently found large coloured diamonds, which includes a pink oval gem weighing 14.83 carats the largest of its kind ever found in Russia. The diamond it was cut from a rough found in 2017 at the Ebelyakh deposit in Yakutia, rated by the American journal The National Jeweler as the best discovery of the year. 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,” Alrosa’s chief executive Yury Okoyemovsaid in a statement. “I am sure that this diamond will be the most expensive in the history of Russia’s gem cutting industry.”
