De Beers Group is advancing the delivery of its business streamlining by setting out a planned portfolio and some organisational changes.

The company says these are set to ensure an efficient cost base that strengthens resilience for the short-term, but will also enhancing future competitiveness and retaining optionality as industry conditions improve.

Since 2024, De Beers has been streamlining its business in line with its Origins strategy to reduce costs, divest non-core assets and prioritise investment in activities that create the most value.

To date, the group reports that over $100 million (£87 million) of annual overhead costs have been removed from the business, a number of non-core assets sold or closed, as well as capital and cost reconfigurations set out to make room for expansion projects.

Moreover, De Beers has reinvested in natural diamond category marketing to boost natural diamond demand.

This has materialised in the launch of new campaigns and collaborations with stakeholders across the value chain.

Global consumer demand for natural diamond jewellery returned to growth in 2025, while natural diamond sales increased across US independent jewellers in 2025 and into Q1 2026, led by higher value diamonds and those promoted by De Beers’ Desert diamonds marketing campaign.

On the supply side, global rough diamond production is now decreasing, with several producers closing mines during 2026.

Rough diamond trading conditions are expected to remain challenging in the near-term due to cyclical and industry-specific factors.

De Beers intends to pause production at the Venetia mine in South Africa for two years to reduce costs while also rephasing capital expenditure on its underground project.

This will involve critical infrastructure investment to enhance the capacity and efficiency of the mine, with the intention to support future production growth as business and industry conditions improve.

De Beers is engaging with stakeholders in accordance with relevant requirements and the company’s values as it moves through this process, and will both support impacted employees and continue to invest in its community and Social and Labour Plan commitments.

This proposed action at Venetia mine follows the decision earlier this year to pause the Tuzo Phase 3 expansion project at the Gahcho Kué mine in Canada.

The company is also planning to reconfigure its global operating model to refocus and prioritise resources on the core operational businesses and reduce its central corporate cost base.

The De Beers Group CEO, Al Cook, said: “In line with our commitment to focus and streamline our business, we are making a number of changes to De Beers to ensure greater business resilience in the near-term, while supporting long-term value creation.

“We recognise the protracted challenging conditions as the diamond industry evolves, though we are encouraged by signs of consumer demand growth in the US and beyond, particularly in higher quality diamonds.

“Global rough diamond supply is falling, bringing more support to the market. The changes we are making to our business are focused on underpinning our efficiency now and into the future, favourably positioning De Beers in its leadership role.”
