The Diavik Stars of the Arctic: Rio Tinto and Dominion Diamond Mines have announced that three of their most spectacular diamonds, produced from the jointly-owned Diavik Mine in Northwest Territories, Canada, will be sold at auction on October 25, 2018. The collection is known as "The Diavik Stars of the Arctic" and includes: "Vega of the Arctic", a 177.71-carat diamond which they report is "one of the largest and most valuable gem-quality rough diamonds ever produced in Canada"; "Altair of the Arctic", a 59.10-carat diamond; and, "Capella of the Arctic", a 24.82-carat yellow diamond, which is an extremely rare find. In an average year, the Diavik mine only produces about five large yellow diamonds, representing less than 0.001 percent of annual production. Photo by Rio Tinto.
ALROSA 14.83-Carat Pink: In February 2019, ALROSA announced that they plan to sell a pink oval-cut diamond weighing 14.83 carats. It is the largest pink faceted diamond ever produced in Russia. It was cut and polished in Russia from rough mined at the Ebelyakh alluvial deposit in Yakutia, Russia. ALROSA has been producing and selling a lot of colored diamonds over the past few years; it is possible that they will become the world's best-known source once the Argyle Mine closes sometime after 2020.
