Statistics · Production
Global diamond production —
the Kimberley Process numbers.
The world mined 98.8 million carats of rough diamonds worth $9.23 billion in 2025 — down about 8% by volume from 2024 — with Russia first by both volume and value, Angola the only major producer that grew, and India importing more rough carats than the entire year's world production. Every figure on this page was read directly from the Kimberley Process Annual Global Summary PDFs, the primary dataset participant governments report into, and was last verified on July 4, 2026.

The one-line read: the natural side of the industry is mining less and holding value — volume fell about 8% while the average per-carat value rose to $93.43 — which is the supply discipline behind the natural prices in our lab-grown vs natural price statistics.

Russia remains first by both measures despite cutting output hardest, and the middle of the table tightened: Angola's 15.2 million carats now sit within rounding distance of Botswana's 15.5 million. Canada holds fourth by volume at a distinctly low $63.28 per carat — large mines, commercial-grade goods — while the Democratic Republic of Congo's 8.9 million carats are worth just $5.01 each, almost entirely artisanal industrial-grade production.

Volume fell three times faster than value: 8% fewer carats but only 3% fewer dollars, because the average carat mined in 2025 was worth 6% more than in 2024. Russia and Botswana each cut roughly a sixth of their volume — the same scarcity defense De Beers' own results describe — while Angola grew 8% into the gap. Producers are managing a smaller, richer stream of rough, not racing for tonnage.

The spread between origins is a factor of nearly seventy: Namibia's marine-recovered goods average $343.88 per carat against the DRC's $5.01. For anyone reading headlines, this is the number that explains why "millions of carats" means little without a value column — and why a polished stone's certificate, not its origin story, is what a store should price against.

India imported more rough carats in 2025 than the world mined — possible because stones pass through trading hubs and are counted again — and re-exported only a seventh of them as rough. The rest feeds the cutting factories, centered on Surat, that turn nearly every gem diamond sold in North America. The UAE line shows the hub economics in one row: 91 million carats in at $78.49, 90 million out at $103.56.
Where Clazoire fits
Our stake, stated plainly.
Clazoire manufactures in Surat — inside the cutting hub these flow statistics describe — setting natural diamonds with GIA certificates and lab-grown with IGI, factory-direct to North American retailers with minimums from 1 unit on most styles. We publish these statistics because our buyers price against them, the same way we publish a dated wholesale gold price index so a store can check our math. Open a wholesale account if the numbers make the case; cite the page either way.

Each figure states the period it covers and was last verified against its primary source on July 4, 2026. Figures that could not be traced to a primary source were dropped rather than estimated.

The Specifics
The numbers, answered straight.
Russia, by both volume and value: 31.5 million carats worth $2.72 billion in 2025, per the Kimberley Process Annual Global Summary. Botswana (15.5 million carats, $1.98 billion) and Angola (15.2 million carats, $1.81 billion) follow — and Angola was the only major producer whose output grew year on year.
98.8 million carats of rough diamonds worth $9.23 billion in 2025, per the Kimberley Process — down about 8% by volume from 2024's 107.9 million carats, as major producers cut output into a weak market. The average value across all production was $93.43 per carat.
Namibia, among major producers: $343.88 per carat average production value in 2025, with Lesotho close behind at $330.90 — roughly four times Russia's $86.46 average and nearly 70 times the Democratic Republic of Congo's $5.01. Origin drives per-carat value more than any other production statistic.
Overwhelmingly in India. In 2025 India imported 106.1 million rough carats — more carats than the entire year's world production, once re-trading through hubs is counted — on 19,091 import certificates, the most of any Kimberley Process participant, while exporting only 15 million rough carats. The difference feeds the cutting industry centered on Surat.
Yes, by volume: 107.9 million carats in 2024 to 98.8 million in 2025, down about 8%, with Russia down about 16% and Botswana down about 15%. Value fell less (about 3%, to $9.23 billion) because the average per-carat value rose — producers are mining less and holding value rather than chasing volume.
