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 to Sell all High-Value Diamonds through HB Group

Lucara is to sell all its larger rough diamonds through the Antwerp-based HB Group in what it describes as a “groundbreaking partnership”.

The Canadian miner has a reputation for high-value type IIa diamonds at its Karowe Mine, in Botswana, and was proud to announce its discovery of the 1,758-carat Sewelo (pictured), the world’s second largest diamond, last April.


It has been stockpiling all +10.8 carats, which account for around 70 per cent of its output, since early March.


Now it has announced a unique, new supply arrangement, with purchase prices based on estimated polished outcome, with a true up paid on actual achieved polished sales thereafter, less a fee and the cost of manufacturing. 

 Lucara says it will benefit higher prices than it currently achieves at tender, regular cash flow, and a more efficient supply chain as well as tax benefits and beneficiation opportunities for the Botswana government.


Eira Thomas, CEO said: “Building on the partnership established for the manufacturing of the Sewelô earlier this year, Lucara is pleased to have now secured a broader supply agreement with HB to purchase all of our +10.8 carat rough diamonds, through to year-end. 

“It is our strong view that the success of our industry in these very uncertain times, requires better alignment between producers, manufacturers, and retailers to establish a healthier, more efficient global diamond supply chain.

We are excited to be working with HB to support this new paradigm.”
