Lucara Diamond Corp. has unearthed yet another exceptional diamond at its Karowe Diamond Mine in Botswana - the latest is an unbroken 549 carat white diamond "of exceptional purity". It is the fourth largest diamond ever recovered at the Karowe mine, the third largest gem-quality stone (the Sewelô is of 'near-gem quality) and already Lucara's sixth diamond larger than 100 carats recovered in 2020. According to independent analyst Paul Zimnisky's estimates, it is only the 4th gem-quality stone exceeding 500 carats recovered globally in the last 5 years.
The recovery follows the recent recovery of a gem quality 176-carat stone from the same ore block, the EM/PK(S) unit of the South Lobe, which also produced other high value diamonds including the 1,758 carat Sewelô, the 1,109 carat Lesedi La Rona, and the 813 carat Constellation diamond. The 549-carat diamond was recovered in the MDR (Mega Diamond Recovery) XRT circuit that allows for diamond recovery post primary crushing and prior to milling. It is the second diamond recovered from the MDR which was commissioned in 2017. Lucara said it will undertake a decision on the sale of the 176 and 549 carat diamonds in due course.
"Lucara is extremely pleased to be starting off 2020 with the recovery of two, large, high quality diamonds that builds on the positive momentum generated following the completion of a strong 4th quarter sale in December and the announcement of our ground breaking partnership with Louis Vuitton on the Sewelô in January," said Eira Thomas, Lucara's CEO. "The unbroken 549 carat diamond is the fourth largest diamond recovered at Karowe and the first large gem to be recovered through the MDR. We look forward to continued success at Karowe and an exciting 2020."
