Diamonds are often associated with love, luxury, engagement rings and expensive jewellery. However, beyond their beauty and commercial value, these precious stones play a significant role in the economies, histories, and international relationships of several countries.
Although diamonds are found in many countries, not every country has the same level of production or influence in the global diamond market.
Countries where diamonds are found
1. Russia
Russia is one of the world’s leading diamond-producing countries. Its diamond deposits are concentrated mainly in the Siberian region, particularly the Sakha Republic, also known as Yakutia.
The country has extensive diamond reserves and is home to ALROSA, one of the world’s largest diamond mining companies. Russia’s position in the diamond industry has also attracted international attention because of sanctions imposed following its invasion of Ukraine. These restrictions have affected the international trade in Russian diamonds and raised questions about the sourcing and traceability of precious stones.
2. Botswana
Botswana is one of Africa‘s most important diamond-producing countries and has built much of its economic success around the industry.
The country is home to some of the world’s most valuable diamond mines, including Jwaneng and Orapa. Its partnership with De Beers through Debswana has played a major role in developing its diamond sector.
Unlike countries where mineral wealth has contributed to prolonged instability, Botswana has used diamond revenue to support infrastructure, education, healthcare and national development. Nevertheless, its dependence on diamonds presents economic challenges, particularly when global demand and prices decline.
3. Angola
Angola is another major diamond-producing country in Africa. Its diamond deposits are found mainly in the northeastern part of the country, particularly Lunda Norte and Lunda Sul.
After decades of civil war, Angola has continued to develop its diamond industry as part of its efforts to diversify its economy beyond oil. The Catoca mine is among its most significant diamond operations.
The country has attracted foreign investment and is working to increase local participation in mining activities. However, concerns about transparency, illegal mining and the distribution of mineral wealth remain important issues.
4. South Africa
South Africa has a long and significant history in the global diamond industry. The discovery of diamonds in Kimberley in the nineteenth century transformed the country’s mining sector and contributed to the growth of its economy.
The country is associated with some of the most famous diamonds ever discovered, including the Cullinan Diamond, which was found in 1905. South Africa remains an important diamond-producing and processing country, although its production has declined from its historical peak.
Its diamond heritage is also closely connected to the development of modern mining and the history of colonialism in southern Africa.
5. Democratic Republic of Congo
The Democratic Republic of Congo is rich in natural resources, including diamonds. Its diamond deposits are found in several provinces, particularly Kasai and neighbouring areas.
A significant portion of the country’s diamond production comes from artisanal and small-scale miners who use relatively basic equipment to extract stones.
Despite its enormous mineral wealth, the country continues to face challenges involving illegal mining, poor working conditions, smuggling and conflict in some regions. Its diamond industry highlights the difficulties of turning natural resource wealth into widespread economic prosperity.
6. Namibia
Namibia is known for its high-quality diamonds, particularly those recovered from marine deposits along its Atlantic coastline.
The country’s diamond industry is distinctive because some of its most valuable stones are recovered from the seabed rather than conventional land-based mines.
Namibia has developed partnerships between the government and private mining companies to manage its diamond resources. Its marine diamond operations have helped establish the country as an important supplier of high-quality stones.
7. Canada
Canada is one of the important diamond-producing countries outside Africa. Its diamond industry developed significantly following discoveries in the Northwest Territories during the 1990s.
Major mines have included Ekati and Diavik. Canadian diamonds are often marketed on the strength of their traceability and responsible sourcing standards.
The country has demonstrated that diamond production is not limited to traditionally recognised mining regions in Africa and Russia.
8. Australia
Australia has a notable history in diamond production, particularly through the Argyle mine in Western Australia. The mine became famous for producing rare pink diamonds, which attracted international attention and commanded exceptionally high prices.
Although the Argyle mine closed in 2020, Australia remains an important part of diamond mining history. The country has also explored and developed other diamond deposits.
Other countries with diamond deposits
Beyond these major producers, diamonds have also been discovered in several other countries, including Zimbabwe, Lesotho, Sierra Leone, Liberia, Guinea, Ghana, Tanzania and Brazil.
Lesotho, for instance, is known for producing large, high-quality diamonds, while Sierra Leone gained international attention for its history of conflict diamonds during its civil war.
Zimbabwe also has significant diamond resources, particularly in the Marange fields, although its industry has faced questions about governance, transparency and revenue management.
