De Beers to pause Venetia diamond mine production for two years

De Beers said on 13 July 2026 that it would pause production at its Venetia mine in Limpopo for two years, citing persistent weakness in the rough-diamond market, and began Section 189 consultations with unions over the resulting job losses. Venetia is South Africa's largest diamond mine by value, and according to De Beers it accounted for 10.3% of the group's total rough-diamond production in 2025, when it produced 2.23 million carats.

De Beers chief executive Al Cook framed the pause as part of a broader restructuring effort. "Our commitment is to focus on value, improve resilience and position De Beers to compete strongly as conditions recover," he said. The company said it would delay spending on an underground expansion project at Venetia while maintaining the infrastructure needed to lift production again once diamond prices recover.

Thousands of jobs affected

Reports following the announcement put the number of jobs at risk at the mine at more than 1,200, out of a total Venetia workforce that runs into the thousands. The National Union of Mineworkers (NUM) criticised the company's handling of the process, with NUM national health and safety secretary Masibulele Naki saying it appeared "deliberate for Venetia management not to communicate" with the union, which he described as the only majority union organising at the mine.

A weak market for rough diamonds

The pause reflects a difficult period for the global diamond industry, squeezed by soft demand, competition from lab-grown stones and an oversupplied rough market. De Beers, majority-owned by Anglo American, has been undergoing a broader operational overhaul as Anglo works to separate the diamond business, and the Venetia decision fits a pattern of the company reconfiguring its global operating model to cut corporate costs.

Part of a broader retrenchment wave

The Venetia announcement landed within weeks of two other major South African mining restructurings: Sibanye-Stillwater's move to close its Kwezi platinum shaft and Petra Diamonds' retrenchments at its Finsch and Cullinan mines. Labour group Solidarity said the three processes together could affect more than 4,000 employees and contractors, warning of a "worrying loss of job security in an industry on which thousands of families and communities depend." For Limpopo's Musina area, where Venetia is one of the largest employers, the two-year pause raises immediate questions about how the local economy will absorb the shock, and whether affected workers will be redeployed elsewhere in De Beers' or Anglo American's South African operations once the mine resumes normal production.
