Size isn’t everything in the diamond market, especially for the biggest gem found in more than a century that took more than a year to sell.

Lucara Diamond Corp. finally sold the 1,109-carat Lesedi La Rona diamond for $53 million, or $47,777 a carat, on Monday to Graff Diamonds, Vancouver-based Lucara said in a statement. While it’s significantly bigger than the 813-carat Constellation stone Lucara found at the same time, that stone sold for a record $63 million, or about $77,500 a carat.
