Lucara Diamond Corp has sold its ‘Constellation’ diamond, weighing in at 813 carats, for an unprecedented $63million – a record for a rough cut diamond.

The Constellation diamond was found in the Karowe mine in Botswana, the same mine where the “Lesedi la Rona” diamond was also discovered in November 2015.  The Lesedi la Rona is expected to bring up to $90million in a June auction this year.

Following the sale, the diamond mining company has entered a partnership with Nemesis International DMCC with Lucara keeping a 10% interest in the net profit of any future sales of the resultant diamonds.

William Lamb, President and CEO of Lucara Diamond Corp, said, "The sale of the 813 carat diamond is the highest price ever achieved for a rough diamond, breaking all records. This achievement solidifies our reputation in the jewellery industry as one of the most important sources of diamonds of the very highest quality."

"We look forward to the next stage of Lucara's development with the sale of the spectacular 1,109 carat, Lesedi La Rona diamond which will take place at Sotheby's London on June 29, 2016." he said.
