Key Highlights
- Worldwide rough diamond output hovers above 100 million carats annually, with 121 million carats reported in 2024.
- In 2025 the five leading producers are Russia, Botswana, Canada, the Democratic Republic of Congo, and Australia.
- Russia supplies over 30 % of global output, while Botswana’s reserves yield high‑grade stones that command premium prices.
- Canada stands out for ethical, traceable mining practices, and the DRC is a major source of industrial‑grade diamonds despite governance challenges.
- Australia’s share is diminishing, yet its rare pink diamonds keep it in the top‑five.
Detailed Insights
The diamond industry remains one of the world’s most valuable mineral markets. Rough diamonds are extracted from deep‑lying kimberlite pipes, polished into gems, and sold either as luxury jewelry or as hardened tools for industrial cutting.
Production figures remain broadly stable. In 2024, rough diamonds exceeded 121 million carats, a figure that typically stays above the 100 million‑carat threshold.
Russia, with its vast mining infrastructure, dominates the sector. Mines such as Udachny, Mirny, Jubilee, and Grib contribute a share greater than 30 % of global production. Modern extraction technologies and a skilled workforce allow Russia to maintain this lead.
Botswana, despite a relatively smaller output, supplies some of the finest gemstones in the world. The Jwaneng and Orapa mines produce a high concentration of large, high‑value stones. The diamond economy underpins the country’s socio‑economic development.
Canada’s reputation for responsibly sourced diamonds has earned it a premium market position. Mines like Diavik, Ekati and Gahcho Gué exemplify strict environmental and labor standards, ensuring traceable origins.
The Democratic Republic of Congo’s Kasai region remains a rich goldmine of industrial diamonds. However, informal extraction and weak regulation raise safety and trade concerns, limiting the country’s potential for global market share.
Australia, known for the former Argyle pink‑diamond mine, continues to produce notable gem‑grade stones, though output is dwindling. The legacy of high‑quality pink diamonds keeps Australia within the top‑five list in 2025.
Key Concepts
- Carat: A unit of weight used for precious stones, equivalent to 200 mg.
- Kimberlite: Volcanic rock that hosts most diamond deposits, forming through deep‑mantle eruptions.
- Industrial‑Grade Diamond: A stone too small or opaque for jewelry, but useful for tools requiring extreme hardness.
- Traceability: The ability to verify a stone’s origin, ensuring ethical and environmental compliance.
- Pink Diamond: A rare variant with a subtle pink hue, prized for its uniqueness and high value.
