Discovered a huge 1,758 carat rough diamond in Botswana

Canada's Lucara Diamond Group recently unearthed the largest rough diamond in more than 100 years of history at Botswana's Karowe mine, larger than a tennis ball.

The 1,758-carat rough diamond weighs nearly 352 grams and is the second largest rough diamond in the world, behind Cullinan Diamond, discovered in South Africa in 1905, according to Lucara's statement.

With this finding, Lucara's shares rose 11.4% to the highest level in more than two months, before closing the trading session on April 25 at 6.3% for $ 1.68, according to Reuters.

Huge rough diamond is the latest discovery in the Canadian company's gem list based in Canada. Since the launch of XRT diamond restoration technology, Lucara has recovered 12 more than 300 carats of diamonds, including a 472 carat and a 327-carat tablet in April 2018.

The 1,109 carat Lesedi La Rona diamond, restored by Lucara in November 2015, disappointed when it was impossible to sell at the June 2016 auction, adversely affecting its stock. Finally, diamond dealer AnhGraff Diamonds bought Lesedi La Rona for $ 53 million in September 2017.

Forbes magazine said that by the end of 2018, Graff had created 67 gems of diamonds from Lesedi La Rona.
