Canada’s largest rough diamond is set to go on display at the Smithsonian National Museum of Natural History in Washington D.C.
The 187.7-carat Diavik Foxfire will appear alongside the famous Hope diamond in the Harry Winston Gallery from November 17 to February 16.
The stone is the largest gem-quality rough diamond recorded in Canada, according to Rio Tinto, which owns 60 percent of the Diavik mine in Canada’s Northwest Territories. The diamond was sold in June to Deepak Sheth of Amadena Investments LLC/Excellent Facets Inc., which chose to keep it in its rough form.
A diamond of the Foxfire’s size would normally not have emerged from Diavik as large gem-quality diamonds were not believed to exist in the region. While Rio Tinto’s mining equipment was configured to hold on to diamonds under 6 carats but crush larger ones, the Foxfire was recovered because its uncommonly flat shaped enabled it to pass through the filters, the Smithsonian said.
“The Foxfire is truly exceptional, one of the great treasures of the Earth,” said Jeffrey Post, curator of the museum’s national gem and mineral collection.
