Lucara Diamond Corp. has unearthed a 36.92-carat “stunning” blue diamond from its Karowe mine in Botswana.
The miner recovered the stone, which is a “high-quality” type IIb, using X-ray transmission machines from ore sourced from stockpile material, it said Monday. Lucara has been seeing increased production of specials from stockpiles, it explained. Since the beginning of January, it has retrieved five stones greater than 100 carats by processing stockpiled ore.
“Lucara is delighted to announce the recovery of this stunning blue, high-quality diamond from the Karowe mine, which again reinforces the special nature of this asset,” said Lucara CEO William Lamb. “Recoveries such as this demonstrate the value contained within the company’s surface stockpiles, which remain an important source of mill feed and a contributor to ongoing diamond recoveries.”
The stone is only the second special blue the company has found at Karowe since it discovered a 9.74-carat blue along with a 4.13-carat pink in 2019. However, the miner, which is known for its large, high-quality rough, did pull up a 37.42-carat, pink, type IIa diamond in August.
The new discovery is a boon for the company, which has been struggling amid the challenging market and a lack of larger stones, which generate higher revenue. In its most recent results, reported earlier this month, the company announced revenue for 2025 dropped 22% to $159.7 million, while profit fell 35% to $26.1 million.
