1,174.76 carat rough diamond

Lucara Diamond Corp. is pleased to announce the recovery of a 1,174.76 carat diamond from its 100% owned Karowe Diamond Mine located in Botswana.

The diamond, measuring 77x55x33mm, is described as a clivage gem of variable quality with significant domains of high-quality white gem material, and was recovered from direct milling of ore sourced from the EM/PK(S) unit of the South Lobe.

The 1,174 carat diamond represents the third +1,000 carat diamond recovered from the South Lobe of the AK6 kimberlite since 2015 including the 1,758 carat Sewelô and 1,109 carat Lesedi La Rona.

The 1,174.76 carat diamond was recovered in the Mega Diamond Recovery XRT circuit. On the same production day, several other diamonds of similar appearance (471 carat, 218 carat, 159 carat) were recovered at the main XRT circuit, indicating the 1,174 diamond was part of a larger diamond with an estimated weight of > 2000 carats.

The MDR is positioned after the primary crusher, ahead of the autogenous mill, and is the first opportunity for diamond recovery within the circuit.

Lucara recovers 341 carat white diamond

341 carat white diamond found at the Karowe mine in Botswana

Canada’s Lucara Diamond has found an unbroken 341-carat white gem-quality rock at its prolific Karowe mine in Botswana, with analysts estimating it could fetch more than $10 million.

The Vancouver based miner said the diamond was recovered over the Christmas period from milling of ore coming from the south western quadrant of Karowe’s South Lobe.

The diamond is the 54th stone over 200 carats recovered at Karowe since it began commercial operations in 2012.

The find builds on previous historic recoveries which include the 342-carat Queen of the Kalahari, the 549 carat Sethunya, the 1,109 carat Lesedi La Rona found in 2015, and the 1758 carat Sewelô, recovered in 2019.

Beyond Sewelô, the only larger diamond ever unearthed is the 3,106 carat Cullinan Diamond, discovered in South Africa in 1905. The Cullinan was later cut into smaller stones, some of which now form part of British royal family’s crown jewels.
