Diamonds were initially mined in ancient India, with the Golconda region being the earliest known site dating back to at least the 4th century BC. Golconda produced famous diamonds like the Koh-i-Noor and the Hope Diamond. Despite India's historical significance, the global diamond trade shifted with discoveries in Brazil in the 18th century and South Africa in the 19th century.
Today, diamonds are mined across the globe, each region contributing to the world's supply in its own way. South Africa has a storied history in diamond production, with kimberlite pipes and alluvial deposits. Botswana has some of the world's largest diamond mines, notably in Orapa and Jwaneng.
Despite challenges, the Democratic Republic of the Congo (DRC) holds valuable alluvial diamond reserves. Angola stands out for its diamond mines, particularly in the Lunda Norte province, while Namibia specialises in marine diamond mining along its coastline.
Russia plays a significant role in diamond production, with key mines like Mir and Udachnaya in the Sakha Republic (Yakutia).
Diamond mines in Canada are primarily located in the Northwest Territories. Some of the diamond mines in this region include the very remote Diavik and Ekati mines.
Australia, with its focus on kimberlite and lamproite deposits, housed the renowned Argyle mine until its recent closure in 2020.
Other countries such as Brazil, Venezuela, and Zimbabwe also participate in the diamond trade, collectively meeting global demand.
