Lucara, a Canadian mining firm, just sold a massive 813 carat diamond for $63 million dollars. This is the highest sale price ever for a rough diamond. But the Constellation diamond actually pales in comparison to the Lesedi La Rona, which Lucara will auction off in June.
The diamond sold this week was named "The Constellation" and was found in the wildly successful Karowe mine in Botswana in November 2015. As part of the sale to purchaser Nemesis International DMCC, Lucara retained a 10% interest in the diamond.
But the best is yet to come. The same mine produced Lesedi La Rona, a 1,109 carat diamond, which is the second-largest "gem quality" diamond ever discovered. Like The Constellation, Lesedi La Rona was discovered in November 2015. Lesedi La Rona will be sold at auction on June 29, 2016 at Sotheby's London.
