Which African Nations Export the Most Diamonds?

Diamonds remain one of Africa’s most valuable natural resources, shaping economies, creating jobs, and funding national budgets. Across the continent, the diamond trade has built schools, hospitals, and entire towns, but it has also exposed challenges such as unstable prices and uneven wealth distribution. 

Here’s a look at the African countries currently leading in diamond exports and what the trade means for their people and economies.

Botswana 

Botswana remains Africa’s biggest diamond exporter by value. In 2023, the country accounted for around 8% of global rough diamond exports worth about $2.9 billion.

Most of Botswana’s diamond production comes from Debswana, a 50/50 partnership between the government and the global diamond company De Beers. 

For decades, diamond income helped Botswana transform from one of the poorest nations in the 1960s into one of Africa’s most stable economies. The money built hospitals, roads, and funded public projects.

However, in 2024, Botswana faced a sharp decline in sales, forcing the government to rethink its spending plans. For many people in Gaborone, this meant slower government contracts and tighter budgets, a reminder of how heavily the country still relies on diamonds.

Angola 

Angola is another major player in Africa’s diamond market, exporting about $5 billion worth of diamonds in 2023. The country’s rich deposits are found mainly in Lunda Norte and Lunda Sul, where the Catoca mine, one of the world’s largest operates.

Diamond trading in Angola is managed by SODIAM, the state-owned company. The sector supports thousands of jobs and local economies in mining regions, but it also faces issues such as poor transparency and unsafe conditions for artisanal miners.

Recently, reports have shown that Angola’s diamond stockpiles are growing due to weaker global demand. Despite this, the government continues to collect significant taxes from the sector, using it as a lifeline for public revenue.

South Africa 

South Africa, historically known as the birthplace of the diamond rush, remains one of Africa’s top exporters. In 2024, the country’s diamond exports were valued at about $1.58 billion.

Unlike most countries that export mostly rough stones, South Africa also sells polished diamonds and supports small jewellery businesses, especially in traditional mining towns like Kimberley.

However, the industry faces high production costs and fluctuating global prices, which have made companies rely more on short-term contracts rather than permanent jobs.

Namibia 

Namibia’s diamonds are unique, many of them are mined offshore along the Atlantic coast. In 2023, the country exported close to $1 billion worth of diamonds.

The sector is largely controlled by Namdeb, a partnership between the Namibian government and De Beers. 

Diamond income has funded infrastructure and social programs, improving living standards in many communities.

But challenges remain. The country’s diamond reserves are aging, and global prices have been weaker in recent years. In 2025, officials even discussed lowering royalties to help keep operations afloat and protect jobs in coastal towns.

Zimbabwe

Zimbabwe’s diamond story is one of both opportunity and controversy. In 2023, the country exported about $489 million worth of diamonds, mainly from the Marange fields.

The diamond boom once brought sudden wealth and employment, transforming local communities. 

But it also sparked disputes over land, lack of transparency, and questions about how much of the money actually benefits ordinary citizens.

Export values have since become unstable, with monthly trade data showing frequent ups and downs.

What you should know

These rankings are based on export value, not the number of carats produced. Diamond prices can change quickly depending on size, quality, and market trends. 

Also, some countries export through trading hubs in Belgium, India, or the UAE, which can make it hard to know exactly where a diamond was mined.

Official data from the Kimberley Process and national trade agencies give a general picture of the industry, but they don’t capture the full story, especially when it comes to informal mining.
