Grandview Klein Diamonds has inaugurated a new diamond manufacturing facility and office in South Africa, expanding its production footprint in one of the world’s key diamond-producing regions.

The new facility, spanning approximately 10,000 square feet, officially opened in late February and currently employs around 50 trained professionals involved in diamond manufacturing operations. The investment reflects the company’s strategy to strengthen cutting and polishing capacity closer to the source of rough supply.

Headquartered in New York, Grandview Klein is a De Beers Group sightholder and maintains manufacturing operations across southern Africa. In addition to the new South African facility, the company operates diamond factories in Botswana and Namibia, along with an office and cutting facility in New York’s Diamond District.

The South African facility integrates advanced manufacturing technologies including precision laser-cutting systems, bruting technology and automated polishing equipment. These technologies are designed to enhance cutting accuracy, optimize rough diamond yield and maintain transparency and compliance throughout the manufacturing process.

According to the company, the investment underscores its commitment to local beneficiation—processing diamonds in the countries where they are mined—while supporting skilled employment and technical development in producing regions.

Commenting on the expansion, Grandview Klein CEO Moshe Klein noted that the company views beneficiation as a core principle of its operations, emphasizing that diamond resources should generate economic opportunities and long-term value for local communities.

A ribbon-cutting ceremony marking the opening of the facility took place on 23 February and was attended by Grandview Klein leadership along with senior executives from the De Beers Group.

The expansion comes at a time when the global natural diamond industry is navigating cyclical market pressures. Industry observers note that continued investment in manufacturing at origin signals confidence in the long-term prospects of the natural diamond sector and its role in supporting producing nations’ economies.
