The 470-carat top light brown cleavage diamond measures 49x42x26mm and it’s Lucara’s third diamond over 300 carats found this year.
It was recovered from the open pit mine’s South Lobe, specifically the EM/PK(S) unit.
Lucara, which owns 100 percent of Karowe, noted it’s recovered a string of large gem-quality stones recently, including five others topping 100 carats: a 265-carat diamond, a 183-carat stone, a 161-carat diamond, a 116-carat diamond, and a 106-carat diamond.
It’s also recovered 13 stones recently weighing between 50 and 100 carats.
Of its entire May production, focused in the EM/PK(S) unit, 12.7 percent of total production weight were diamonds weighing 10.8 carats or more.
Important diamonds like the 1,109-carat “Lesedi La Rona” Graff purchased for $53 million and the 1,758-carat “Sewelô” diamond Louis Vuitton is turning into a jewelry collection were discovered at Karowe.
