Meaning of Diamond Production
Diamond production refers to the extraction of rough diamonds from natural deposits, usually measured in carats. One carat equals 0.2 grams, and production levels in Africa are often expressed in millions of carats annually. Production includes both gem-quality diamonds, which are used in jewelry, and industrial-quality stones, which are applied in drilling, cutting, and grinding industries.
Importance of Africa in the Global Diamond Industry
Africa has historically been the world’s leading supplier of diamonds, and the continent remains dominant today. While countries outside Africa such as Russia and Canada are large producers, the African continent contributes more than half of global gem-quality stones. Mines such as Jwaneng in Botswana, Venetia in South Africa, and Catoca in Angola are among the most productive worldwide.
Top 10 Diamond Producing Countries in Africa
1. Botswana
Botswana is Africa’s leading diamond producer, with annual output of about 25.1 million carats. The country is home to the Jwaneng and Orapa mines, operated by Debswana, a partnership between De Beers and the government of Botswana. Diamonds account for a significant portion of Botswana’s GDP and have transformed it into one of the most stable economies in Africa.
2. Democratic Republic of Congo
The Democratic Republic of Congo (DRC) produces between 8.3 and 9.9 million carats annually, making it the second-largest African producer. Most of its diamonds are industrial grade, sourced largely from the Kasai region. Despite vast reserves, challenges such as artisanal mining dominance and regulatory difficulties affect the sector.
3. Angola
Angola produces around 9.8 million carats annually, ranking third in Africa. The Catoca mine, operated in partnership with Russian firms, is one of the world’s largest kimberlite mines. Angola’s government is working to increase transparency and attract investment to boost diamond revenues.
4. South Africa
South Africa produces about 5.9 million carats annually. Historically famous for mines such as Kimberley and Cullinan, the country remains a significant producer. Venetia mine, operated by De Beers, is currently the largest source of diamonds in South Africa.
5. Zimbabwe
Zimbabwe contributes approximately 4.5 million carats each year, with most production centered in the Marange diamond fields. While controversial due to past governance and human rights issues, Zimbabwe’s output remains one of the highest in Africa.
6. Namibia
Namibia produces 2.1–2.3 million carats annually, with a unique focus on marine mining. De Beers Marine Namibia extracts diamonds from the Atlantic seabed, making the country’s industry one of the most technologically advanced in Africa.
7. Sierra Leone
Sierra Leone produces around 600,000–700,000 carats annually. Known historically for “blood diamonds,” the country has made significant progress in reforming its industry. Major mining areas include Koidu and Tongo.
8. Lesotho
Lesotho contributes about 0.7 million carats annually (≈700,000 carats), but its global significance comes from the high quality and large size of stones mined at Letseng. Diamonds from Lesotho often fetch premium prices on the international market.
9. Ghana
Ghana produces between 300,000 and 400,000 carats annually. While small in volume compared to major producers, Ghana’s diamonds are primarily gem-quality and mined through both industrial and artisanal operations.
10. Tanzania
Tanzania produces around 200,000–300,000 carats annually, mostly from the Williamson diamond mine. While production is modest, the country is known for steady contributions to Africa’s diamond exports.

Characteristics of African Diamond Mining
- Concentration of Production – A few countries such as Botswana, Angola, and DRC dominate Africa’s diamond output.
- Mix of Mining Scales – Africa combines large-scale corporate mines with widespread artisanal mining.
- Gem vs. Industrial Diamonds – Nations like Botswana focus on gem-quality stones, while DRC supplies mostly industrial-grade.
- Technological Diversity – From traditional artisanal methods to advanced marine mining in Namibia, Africa displays a range of techniques.
Challenges of Diamond Production in Africa
- Artisanal Mining Issues – Informal miners often lack regulation, leading to smuggling and lost revenue.
- Conflict Legacy – Countries like Sierra Leone and Liberia faced challenges with conflict diamonds.
- Governance and Transparency – Weak institutions and corruption sometimes undermine diamond revenues.
- Environmental Impact – Mining often causes land degradation, water pollution, and deforestation.
Future Outlook of African Diamond Industry
Africa’s diamond production is expected to remain strong due to large reserves and ongoing exploration. Investments in technology, transparency programs like the Kimberley Process, and responsible mining practices are improving the industry’s image. Countries such as Botswana and Namibia are also moving toward local beneficiation, where more diamonds are cut and polished domestically, adding economic value.
