• Sacim sells 288,000 carats in first Antwerp public sale

• Marks return of Congolese diamonds after decade absence

• Follows 2025 trading liberalization, amid falling exports

Anhui Foreign Economic Construction Ltd Congo Corp (SACIM) has completed its first public sale of 288,000 carats of industrial diamonds in Antwerp, Belgium, the Consulate General of the Democratic Republic of Congo in the city said.

The sale was held from Feb. 16 to Feb. 20, 2026, with technical support from Belgian firm Samir Gems, active in the diamond and jewelry trade, and the Antwerp World Diamond Centre (AWDC). A total of 67 international companies took part, with leading buyers from China, India, the United States and Italy.

The transaction marks the return of Congolese industrial diamonds to the Antwerp market after more than a decade, the Consulate said. However, the interruption did not affect all exports. Official statistics show Belgium among the importers of Congolese industrial diamonds in 2024 and 2025, with 3.96 million and 1.7 million carats respectively.

Following the sale, Sacim, Samir Gems and the AWDC agreed on an annual schedule of public sales and a framework for technical and institutional support aimed at strengthening the long-term presence of Congolese diamonds in Antwerp.

The sale comes eight months after the liberalization of diamond trading by Congolese producers. In June 2025, then-Minister of Mines Kizito Pakabomba repealed a 2022 decree that regulated mineral sales through the Center for Expertise, Evaluation and Certification of Precious and Semi-Precious Mineral Substances (CEEC). The framework limited producers to a restricted list of buyers, a system that could influence prices. As a major player in the sector, Sacim was among the companies most affected.

The terms of the Antwerp sale were not disclosed. Official 2025 mining statistics nonetheless show an improvement in Sacim’s average sales price. In 2024, when the sector’s average price stood at $9.63 per carat, Sacim recorded $11.38. In 2025, the company maintained an average price of $11 while the sector average fell to $7.4 per carat. Natural diamond prices have been declining for several years.

According to official data, exports by Sacim, jointly owned by China’s Anhui Foreign Economic Construction Corporation (AFECC) and the Congolese state, were halved, falling from 2,887,100.25 carats in 2024 to 1,151,865.58 carats in 2025. The company accounted for 13.5% of national output, producing just over 1.1 million carats.
