De Beers leaves rough prices unchanged at the first cycle of the year
De Beers left rough prices unchanged at the first cycle of the year after December’s sharp reductions. It allowed 20% buybacks for all goods — a mechanism that lets sightholders sell the least profitable stones back to the company. Demand was weak, with sales value expected to be low.
But the question on sightholders’ lips was what would happen next. One of the main reasons for the low sales was De Beers’ high prices. The miner’s rough remains significantly more expensive than the tender and auction market.
The company’s December price change of 10% to 15% went only part of the way toward closing this gap. Russian rival Alrosa has now reached similar price levels: It followed a December cut of around 10% with a further one of 7% to 8% in January, market insiders said.

De Beers Rough Diamond Production Up 17 Year-on-Year
The Sequential Recovery Was Even More Striking, With Output Climbing 88% Quarter-on-Quarter From a Heavily Suppressed Q4 2025 Baseline
De Beers rough diamond production up 17% year-on-year to 7.1 million carats for the quarter ended March 31, 2026, is the kind of figure that reads well in a headline. But context transforms interpretation. The sequential recovery was even more striking, with output climbing 88% quarter-on-quarter from a heavily suppressed Q4 2025 baseline — a rebound that reflects operational factors rather than any meaningful surge in consumer demand for natural diamonds.
Both primary growth drivers were operationally predetermined rather than market-responsive. A planned ore release from a new area at the Gahcho Kué joint venture mine in Canada, and the continued processing of higher underground ore volumes at the Venetia mine in South Africa, together accounted for the majority of the year-on-year production increase. These are scheduled outcomes of capital programmes that were set in motion years earlier, not reactive decisions to chase rising diamond prices.
This distinction matters enormously for market interpretation. Production growth driven by mine transition schedules and ore release programmes carries a fundamentally different signal than growth driven by producers ramping up output in response to strengthening demand. In the current environment, De Beers is producing more simply because its mines are at a stage in their operational cycles where more ore is available — not because the market is calling for it.
Furthermore, according to De Beers’ official Q1 2026 production report, the critical distinction for Q1 2026 is that volume and value are moving in opposite directions. A 17% increase in production alongside a 19% decline in average realised price tells a more nuanced story than output data alone can convey. Production guidance for 2026 is unchanged at 21–26 million carats (100% basis). De Beers continues to monitor rough diamond trading conditions in order to align output with prevailing demand. Unit cost guidance for 2026 is unchanged at c.$80/carat
