RAPAPORT... Lucara Diamond Corp. has recovered the largest diamond unearthed in Botswana. The 1,758-carat stone, from the Karowe mine, has been characterized as near-gem, with its quality varying throughout the diamond, Lucara said last week. Portions of it arehigh-quality white gem, the miner explained. The company extracted the stone in an unbroken state using technology that it commissioned in 2015. Since then, Lucara has recovered12 diamonds weighing more than 300 carats, two of which - including this find -were over 1,000 carats. Those stones were both recovered in Karowe'shigh-value south lobe. "Karowe has now produced two diamonds greater than 1,000carats in just four years, affirming the coarse nature of the resource and thelikelihood of recovering additional large, high-quality diamonds in the future,particularly as we mine deeper in the ore body and gain access to thegeologically favorable EM/PK(S) unit, the source of both of our record-breaking,1,000-plus-carat diamonds," Lucara CEO Eira Thomas added.Image: The 1,758-carat diamond.
