BOTSWANA – On Nov. 18, 2015, Vancouver-based Lucara Diamond Corp. announced that it had recovered the world’s second largest diamond, weighing 1,111 carats, from its Karowe mine.

The stone was found in the south lobe of the mine and recovered by the recently installed large diamond recovery XRT machines. It measures 65 x 56 x 400 mm in size. It is the largest diamond ever recovered in Botswana.

William Lamb, Lucara president and CEO, said, “This historic diamond recovery puts Lucara and the Karowe mine amongst a select number of truly exceptional diamond producers. The significance of the recovery of a gem quality stone larger than 1,000 carats, the largest for more than a century and the continued recovery of high quality stones from the south lobe, cannot be overstated.”

The news of such a significant diamond overshadowed the news on Nov. 19 that the company had also recovered two more large white diamonds. One weighed 813 carats and the other 374 carats.
