RAPAPORT... Botswana's largest rough diamond now has a name, following a public contest held by Lucara Diamond Corp. The company chose to call the 1,758-carat stone Sewel??, which means "rare find" in the local Setswana language. It was the winning entry from more than 22,000 submissions. "The largest diamond recovered in Botswana's history wasnamed by the people of Botswana this evening in a celebration of Botswana'ssuccess," Lucara CEO Eira Thomas said last week. The miner has completed its analysis of the diamond - which itrecovered in April from the Karowe mine's high-value south lobe - and isconsidering its sale options, Thomas added. Lucara announced the new name during a gala event, at which Botswana President Mokgweetsi Masisi was present. Image: The 1,758-carat Sewel?? diamond. (Lucara Diamond Corp.)
