Lucara Diamond Corp. has announced the recovery of a rare and unusual pink diamond from its Karowe mine in Botswana.
The 37.42-carat stone, classified as a Type IIa, was unearthed in August and is described as near-gem quality with a distinctive bicoloured appearance. While the majority of the diamond displays an intense pink hue, part of the stone appears partially colourless an exceptionally rare feature.
HB Antwerp, Lucara’s cutting and technology partner, described the discovery as “a rare and remarkable find.” Oded Mansori, co-founder of HB Antwerp, noted:
“This stone has the potential to become one of the most important pink diamonds ever polished. Its intensely rich coloration is a testament to the geological uniqueness of the Karowe mine, and our expertise in the manufacturing process will ensure its vibrant colour is maximised.”
The recovery underscores Karowe’s reputation as a consistent source of exceptional diamonds. Also in August, Lucara recovered a 1,019.85-carat non-gem-quality diamond, the third stone of more than 1,000 carats to be found at Karowe in 2025. This brings the total number of diamonds over 1,000 carats from the mine to nine.
Both diamonds were recovered from the EM/PK(S) section of the deposit using Lucara’s Mega Diamond Recovery (MDR) unit, an advanced X-ray transmission system installed in 2017 to identify and preserve large stones. The MDR is credited with detecting several of Karowe’s most significant recoveries, including the 2,492-carat diamond discovered in August 2024—the second-largest rough diamond ever found.
Meanwhile, Lucara has announced a $10 million drawdown from its $63 million standby loan facility with Nemesia, its largest shareholder, to address short-term funding needs for the Karowe underground expansion project. The $683 million project, now scheduled for completion in the first half of 2028, is expected to extend the mine’s life to at least 2040.
Lucara President and CEO William Lamb said the arrangement reflects the company’s commitment to financial prudence while advancing the underground project.
“This funding mechanism demonstrates the continued confidence and support of our major shareholders in Lucara’s long-term strategy and in the exceptional value potential of the Karowe mine, including the ongoing recovery of some of the world’s most significant diamonds.”
