Canadian mining company Lucara Diamond Corp. has announced the recovery of the second largest diamond in history: a 1,111 carat, gem quality, Type IIa diamond. According to their Nov. 18 press release, "The magnificent stone, which originated from the south lobe of Lucara's Karowe Mine [in Botswana], is the world's second largest gem quality diamond ever recovered and the largest ever to be recovered through a modern processing facility. The stone was recovered by the newly installed Large Diamond Recovery ("LDR") XRT machines. The stone measures 65mm x 56mm x 40mm in size and is the largest ever to be recovered in Botswana."
William Lamb, President and CEO, commented, "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." Lucara also recovered two white diamonds weighing 813 and 374 carats from Karowe using the XRT technology, it added in a separate statement November 19. “This has been an amazing week for Lucara with the recovery of the second largest and also the sixth-largest gem-quality diamonds ever mined,” Lamb said.
