# De Beers halts its flagship South African diamond mine as demand slumps

De Beers is suspending mining at Venetia, its biggest diamond operation in South Africa, for two years, putting thousands of jobs at risk as a prolonged slump in demand and the rise of lab-grown stones batter the natural-diamond market.

De Beers, the world's largest diamond producer, is halting mining at its flagship South African operation for two years, a decision that lays bare the depth of the slump gripping the natural-diamond industry.

The company said it would pause production at the Venetia mine in Limpopo province, [South Africa's largest diamond source](https://www.mining.com/de-beers-idles-south-africas-top-diamond-mine-for-two-years/), while keeping essential infrastructure in place so it can restart quickly if demand recovers. Venetia produced about 2.23 million carats in 2025, a significant share of De Beers' global output.

## Thousands of jobs at risk

The suspension threatens roughly 3,500 jobs at the site, and De Beers has begun formal retrenchment consultations with workers and unions, [according to South Africa's Business Day](https://www.businessday.co.za/companies/2026-07-14-de-beers-plan-to-shut-sa-operations-spells-pain-for-anglo-american/). The final number of positions affected has not been settled. For the surrounding communities in northern South Africa, where the mine is a major employer, the pause is a heavy blow.

The company has framed the halt as temporary, deferring investment in Venetia's planned shift to underground mining rather than abandoning it. The mine's reserves are expected to support operations into the 2040s once that conversion is complete.

## A market under pressure

The move reflects a sharp downturn in the diamond trade. Natural diamond prices have fallen far from their 2022 peak, squeezed by weak luxury spending, particularly in China, and by the rapid rise of lab-grown stones. Those synthetic diamonds, [physically near-identical to mined ones but far cheaper](https://www.bloomberg.com/news/articles/2026-07-13/de-beers-to-shutter-south-african-diamond-mine-to-save-cash), now account for a large and growing share of the US engagement-ring market.

De Beers has responded by cutting prices and paring back the number of buyers it sells rough diamonds to, moving away from its long-standing strategy of holding prices firm even as demand softened.

## Strain on Anglo American

The crisis has weighed heavily on Anglo American, the mining group that owns De Beers and has been looking to offload the business as it reshapes its portfolio. Anglo has written down the value of the diamond unit substantially over the past few years amid the downturn.

Whether Venetia's two-year hiatus proves the right call depends on a recovery that remains far from certain. Analysts caution that the shift toward lab-grown stones and changing consumer tastes may represent a structural change in the market rather than a passing dip, leaving the timing of any rebound in doubt.
