Jwaneng: Botswana’s Crown Jewel and Largest Diamond Mine by Value (2025)
Situated in the arid landscape of the Kalahari Desert, the Jwaneng Mine in Botswana is operated by Debswana, a joint venture between Botswana’s government and De Beers. By 2025, Jwaneng remains the world’s largest diamond mine by value, thanks to its exceptional ore quality and consistent output of high-grade gem-quality diamonds.
- Located in the Kalahari Desert, amplifying socio-economic impact in southern Africa
- Output: More than 10 million carats annually
- Deep integration of automated extraction and remote sensing technology in operations
- Renowned for producing some of the world’s most valuable and exceptional diamonds
- Contributes significantly to Botswana’s GDP, providing crucial employment and revenue
Mines with a high ratio of gem-quality diamonds—like Jwaneng—offer resilient market value even during global downturns, making them essential to investment portfolios focused on precious resources.
Jwaneng’s Economic and Social Impact
- Providing over 2,000 jobs directly and thousands more indirectly
- Generating over $3 billion in annual revenues
- Supporting local infrastructure, health, and education projects
Through its strategic scale, technological edge, and ethically managed output, Jwaneng is the blueprint for modern diamond mining heading toward 2026.
Udachny: Russia’s Massive Producer (Sheer Physical Size)
When discussing the largest diamond mine in the world by physical size, the Udachny Mine in the Sakha Republic (Yakutia), Russia, stands as an imposing giant. Operated by ALROSA, a global leader among diamond exporters, Udachny is a hybrid of vast open-pit operations and deep underground mining.
- Located in eastern Siberia, within Yakutia, an area famous for extreme geology
- Covers a massive area with some of the world’s largest extraction facilities
- Output: 8–10 million carats annually (2025 estimate)
- Pioneers in automated underground mining and deep shaft operations
- Represents Russia’s leadership in high-volume diamond production
Many confuse the largest diamond mine in the world by value (Jwaneng, Botswana) with the largest by physical area and volume (Udachny, Russia). They represent different dimensions of scale and significance in the global diamond sector.

The Largest Diamonds Mined in the World: Historic Stones & Their Legacy
The Cullinan Diamond—discovered in 1905 at South Africa’s Premier Mine—remains unmatched as the largest diamond found in the world in its original rough form. Weighing a jaw-dropping 3,106 carats (621 grams), it sent shockwaves through the global diamond market and continues to define the upper limit of what is geologically possible.
- Largest Diamond Mined in the World: Cullinan (South Africa, 1905, 3,106 carats)
- Cut Into: Several polished gems, including the Great Star of Africa (Cullinan I), now set in the British Crown Jewels
- Other Legendary Finds: Lesedi La Rona (Botswana, 1,109 carats), Excelsior (South Africa, 995.2 carats), and the recent 1,500-carat stone (2025)
The Cullinan Diamond was so large that a railway wagon was specially built and armed guards deployed to deliver it safely to the UK for cutting!
