Biggest gem found sells for millions less than expected

The diamond was found on 16 November 2015, in the South Lobe of the Karowe mine about 200 m below the surface, and the find was announced on 18 November. A day after the discovery, two more diamonds weighing 813 and 374 carats were found in the mine.

It took more than a year for Canadian miner Lucara to sell the stone proving that size isn’t everything in the diamond market.

Canadian miner’s tennis ball-sized 'diamond in the rough' proves too big to sell. A diamond may be forever for some but for millennials it's looking like not so much

Freakish fluke that 187-carat diamond pulled from Canada’s Arctic ice was ever found
Size isn’t everything in the diamond market, especially for the biggest gem found in more than a century and which took more than a year to sell.

Lucara Diamond Corp. finally sold the 1,109-carat Lesedi La Rona diamond for US$53 million, or US$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 US$63 million, or about US$77,500 a carat.

The fate of the Lesedi, or “our light” in the Tswana language spoken in Botswana, is a good example of how size isn’t the most important factor in the the diamond industry. The gem is more difficult to cut and the colour isn’t as good as the Constellation, meaning it probably won’t yield as good a polished stone. BMO Capital Markets had forecast that the diamond, which went unsold at a Sotheby’s auction in London last year, could sell for US$75 million.

“If you take the potential outcomes from the stone into consideration, the risk that the buyer is actually taking, you can now see why it wasn’t the easiest one to sell,” Lucara Chief Executive Officer William Lamb said in a phone interview.
