Records as they say, are meant to be broken. The latest iteration of this quote has manifested via the unveiling of what people are now calling the largest graded D-color emerald-cut diamond on record.
The VVS clarity "Constellation 1", one of several stones fashioned from the famous 813ct Constellation rough diamond (pictured below), is now the current record holder of this esteemed title. The finished emerald-cut diamond weighs about 313 carats, and its cutting was the initiative project of Nemesis International in partnership with Swiss company de Grisogono- which originally purchased the stone for a bit over sixty three million dollars back in 2016.
After a period of 18 months spent on the careful examination of the original material's inclusions and their positions, Almas Diamond Services, sister company to Nemesis International, pushed through with the cutting process to achieve a 57% recovery rate on the stone.
Such rare diamonds are arriving on the international stage with great promise, especially during a time when the natural diamond industry has slowed globally due to several factors- such as lower demand from Chinese markets as observed during the September 2019 Hong Kong Jewellery Fair.
At the current time, Nemesis has no current plans yet to sell the diamond, expressing its intention to keep the final faceted stones together as a family, possibly sending them on tour as the miniature works of art that they are.
