Long celebrated as Africa’s diamond success story,Botswana is facing its toughest economic challenge in decades. The rise of cheaper, lab-grown gems is eroding demand for natural diamonds, threatening a sector that once accounted for 80% of the country’s exports and a third of government revenue. Across the country, the slowdown is visible. Patients queue for hours outside government clinics as medicine shortages worsen, construction companies fire workers dependent on state contracts and students threaten protests over unpaid allowances.
“We’re spending long periods in the queue and our jobs suffer,’’ said taxi driver Galeemiswe Mosheti, who now waits up to eight hours for diabetes medication that used to take one. The contrast with the past is stark. Since diamonds were first discovered in 1967, Botswana transformed from a rural backwater with only a few paved roads into sub-Saharan Africa’s richest nation per capita. For decades, diamond wealth funded free healthcare, education, and enviable infrastructure, making Botswana a model of stability.
Now, President Duma Boko calls it a “national social existential threat.” He stated, “For decades, we have leaned and relied heavily on diamonds. While they served us well, we know painfully today that this model has reached its limits.” The global diamond market has shifted dramatically. In the US, the world’s biggest buyer, lab-grown stones now make up nearly half of engagement ring sales, up from just 5% in 2019, according to BriteCo. Synthetic gems, grown in weeks in labs, are far cheaper than natural diamonds that take billions of years to form underground. Add to that the collapse of luxury retail in China and tariffs hitting global trade, and Botswana’s diamond-dependent model is reeling.
The fallout is severe. Anglo American, parent of De Beers which mines nearly all of Botswana’s diamonds in partnership with the state is considering selling the business after repeated write-downs. Debswana, the joint venture, is running at just 60% of capacity. The IMF projects Botswana’s fiscal deficit at 11% of GDP this year, the widest in sub-Saharan Africa, with debt nearly doubling to 43% of GDP. Government is scrambling for alternatives.
Boko has declared a public health emergency, engaged consultants to push diversification and courted flashy investment pledges, including a $12 billion promise from Qatar’s Al Mansour Holdings. Yet many analysts doubt the credibility of such deals. Finance Minister Ndaba Gaolathe has launched an unprecedented pitch to pension funds and private investors to finance infrastructure. “Our teams are ensuring that every pula that’s spent goes strictly towards essential goods and services,” said Gaolathe.
But structural challenges run deep. Tourism contributes just 12% of GDP, copper and coal projects struggle to attract funding, and youth unemployment tops 40%. “The diamond sector is under severe pressure, both prices and volumes,” said Ravi Bhatia of S&P Global Ratings. For Botswana, the fear is that unlike oil cycles in Nigeria or Angola, diamond demand may never recover. “The difference with the oil cycle is that diamond prices are unlikely to ever come back. Its economic model is likely to cease being one of the shining lights on the African continent,” said Charlie Robertson, an Economist.
