Deep in the heart of Botswana, where the ochre earth stretches under an endless African sky, lies a treasure trove that has transformed a nation. The Jwaneng Diamond Mine, affectionately dubbed the “Prince of Mines,” isn’t just the richest diamond mine on the planet, boasting an estimated value of a cool billion euros—it’s a glittering testament to how natural resources, when managed with foresight and care, can elevate an entire country.
Nestled within an ancient volcanic crater, some 170 kilometres southwest of the bustling capital, Gaborone, Jwaneng—meaning “a place of gems” in the local Setswana tongue—sits atop a geological marvel: a kimberlite pipe. This subterranean conduit, like a geological elevator, has ferried precious diamonds from the Earth’s deep mantle to the surface for millennia.
The story of Jwaneng began in the 1970s, when the keen eyes of De Beers geologists spotted its potential. Since it roared into operation in 1982, this behemoth of a mine, operated by Debswana—a savvy partnership between the diamond behemoth De Beers and the Botswana government—has unearthed a dazzling cascade of millions of carats from its trio of primary kimberlite pipes. Just last year, in 2023, Jwaneng alone yielded a staggering 13.3 million carats, cementing its reign as the world’s most valuable diamond producer.
But Jwaneng’s impact stretches far beyond mere carats and euros. It has been the bedrock of Botswana’s remarkable economic ascent. This single mine contributes a staggering 70 percent to Debswana’s coffers, and since its inception, it’s estimated to have generated a jaw-dropping $96 billion in revenue. This financial windfall has been instrumental in Botswana’s remarkable journey from one of the world’s poorest nations in the 1960s to the thriving middle-income country it is today.
The scale of operations at Jwaneng is breathtaking. Giant drills relentlessly bore into the earth, loosening the diamond-rich rock, which is then ferried away by colossal trucks to a state-of-the-art processing plant. Here, the rough diamonds are meticulously separated from the ore using cutting-edge technologies, including X-ray and laser sorters—a dazzling display of modern engineering meeting ancient geological processes.
While the immense scale of mining inevitably presents environmental considerations, Jwaneng has notably strived for responsible practices. It proudly became the first operation in Botswana to achieve the coveted ISO 14001 certification for its commitment to eco-friendly initiatives.
Looking ahead, the future of this “Prince of Mines” gleams brightly. The ambitious “Cut-9” project, a €1.5 billion undertaking, is poised to extend the mine’s lifespan until at least 2035, promising an additional 53 million carats. Further bolstering its long-term prospects, an underground expansion, greenlit in January 2024, is projected to create thousands of jobs and inject an estimated €20 billion into the economy in the coming decades.
Jwaneng’s commendable approach to responsible mining sets It apart from many of its global counterparts. Debswana actively reinvests its wealth into Botswana’s very fabric, funding crucial education, healthcare, housing, and even wildlife preservation efforts—a shining example of a resource company understanding its broader societal obligations.
Of course, the challenges of environmental sustainability remain a constant focus, and the company continues to pursue innovative green initiatives to mitigate its impact.
Ultimately, the Jwaneng Diamond Mine stands as a powerful symbol—a vital engine of Botswana’s economy and a beacon of how responsible mining can not only extract precious gems but also cultivate a brighter future for a nation. It truly is a “place of gems” in more ways than one.
