Largest diamond in North America found in N.W.T., says Dominion Diamond https://t.co/26HNRDFs3f pic.twitter.com/sFfvylslv6 — CBC North (@CBCNorth) December 14, 2018The largest diamond ever discovered in North America was unearthed in October, Canadian mining company Dominion Diamond Mines announced in a Thursday news release. Weighing in at 552 carats, the yellow diamond was recovered at the Diavik Diamond Mine, located in Northern Canada about 135 miles south of the Arctic Circle. Dominion Diamond Mines, which calls the gemstone “astonishing,” notes that the previous North American record was held by the Diavik Foxfire — a 187.7-carat gem-quality diamond recovered in the same mine by the Rio Tinto Group. “The color and texture of the diamond are a unique example of the journey that natural diamonds take from their formation until we unearth them,” Kyle Washington, chairman of Dominion Diamond Mines, said in the release. The company owns 40 percent of Diavik Diamond Mine.
