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.
