- Gem Diamonds Limited (LSE: GEMD; OTC: GMDMF), founded in 2005 and headquartered in London, United Kingdom, operates as a global diamond producer focused on high-value rough diamonds from its primary asset, the Letšeng mine in Lesotho, where it holds a 70% interest with the remainder owned by the Government of Lesotho; it also owns the Ghaghoo mine in Botswana, which remains on care and maintenance with a sale process underway. The company produces large, Type II white, top-color diamonds renowned for achieving the world's highest average US dollar per carat value among kimberlite mines, supplemented by occasional high-quality pink and blue stones; core activities encompass open-pit diamond mining and processing at Letšeng via three treatment plants handling 6.4-6.6 million tonnes annually despite low grade recovery, rough diamond sorting, sales and marketing through tenders and multiple channels via Gem Diamonds Marketing Services BVBA in Antwerp, Belgium, high-tech diamond analysis and select manufacturing into polished stones via Baobab Technologies BVBA, and technical, financial, and management consulting services via subsidiaries including Gem Diamond Technical Services (Pty) Limited in Johannesburg, South Africa, and innovation research in Cyprus. Operations span Lesotho, Botswana, the United Kingdom, Belgium, South Africa, and Cyprus, targeting premium international diamond buyers and manufacturers. Recent developments include a revised Letšeng Life of Mine Plan announced in December 2024 that reduces future waste-stripping costs by approximately US$180 million through optimized planning and lower waste volumes, a two-year extension of revolving credit facilities to US$71.7 million involving banks such as Firstrand, Nedbank, and Standard Bank with sustainability-linked terms, strategic cost reductions of 20% via workforce optimization (including 250 job cuts) and executive pay adjustments amid a challenging diamond market, relinquishment of the Ghaghoo mining license to conserve capital, multiple exceptional diamond recoveries in 2024-2025 such as 212.91-carat, 172.06-carat, and 129.71-carat Type II whites, and the appointment of Janet as a non-executive director in April 2025 with audit committee chair responsibilities.
