SODIAM

SODIAM, an abbreviation associated with Sociedade de Comercialização de Diamantes and also described in English as the Diamond Trading Society, is Angola's national diamond-trading company. It was established in November 1999 as a subsidiary of ENDIAMA, the state-owned Angolan diamond-mining company, during the final years of the Angolan Civil War. Its original purpose was to regulate, certify, market, and export diamonds produced in Angola, helping the government distinguish officially controlled production from stones sold by armed groups operating in areas outside effective state control. The company's creation was closely connected to the international conflict-diamond problem. UNITA and other rebel forces controlled important diamond-producing areas during the civil war and used rough diamonds obtained from those areas to acquire weapons and other supplies. In response to attacks on civilians and United Nations personnel, the UN Security Council imposed sanctions on UNITA, including restrictions on Angolan diamonds unless they were certified as originating through the recognized government in Luanda. SODIAM therefore became an institutional mechanism for government certification and a controlled route into international markets. To consolidate this role, SODIAM established the Angola Selling Corporation, commonly known as ASCORP. SODIAM held 51 percent of ASCORP, while the remaining interest was principally associated with Belgium-based Omega Diamonds and the Lev Leviev Group. ASCORP operated as the single export channel for Angolan rough diamonds for a period, and licenses held by other exporters were revoked. When ASCORP's license expired in 2004, responsibility for marketing and exporting Angolan diamonds returned to SODIAM. SODIAM's responsibilities extend beyond a simple trading office. It brings together production from mines operated through ENDIAMA partnerships and diamonds recovered by artisanal miners, then supports their movement into national and international markets. Its wider operating structure includes the Polo de Desenvolvimento Diamantífero de Saurimo, a logistics and sector-development operation in Lunda Sul; the Centro de Treinamento em Avaliação e Lapidação de Diamantes, a training center focused on diamond valuation and cutting; and international offices or subsidiaries serving major diamond and trading centers, including Antwerp, Israel, Dubai, Shanghai, and Macau. The company has also been involved in diamond-related luxury and investment arrangements. In 2017, it divested its interest in the Swiss jewelry business De Grisogono, citing public-interest and legality considerations. The transaction later became part of wider scrutiny surrounding relationships among Angolan state-linked diamond interests, Isabel dos Santos, and Sindika Dokolo. Reporting connected to the 2020 Luanda Leaks investigation alleged that diamond assets and transactions had benefited politically connected individuals; these allegations and related legal matters should be distinguished from a definitive judicial finding against SODIAM itself. SODIAM remains an important state instrument in Angola's diamond economy. Its functions combine commercial distribution, export administration, sector logistics, professional training, and the formalization of artisanal and industrial production. The company reported exports of approximately 9.9 million carats of rough diamonds in 2023, illustrating the scale of Angola's continuing role in the global rough-diamond supply chain.

SODIAM was founded in November 1999 as a subsidiary of ENDIAMA, Angola's state-owned diamond-mining company. Its formation took place while the Angolan Civil War was still affecting the country's political and economic institutions. UNITA controlled substantial rural territory, including areas with valuable diamond deposits, and rebel forces used diamonds mined in those territories to obtain weapons. The international trade in such stones became a major source of concern because it allowed armed groups to finance conflict while presenting diamonds as ordinary commercial goods. The United Nations Security Council responded to UNITA's attacks on civilians and United Nations personnel with sanctions that included an embargo on diamonds from Angola unless they were certified as authentic and authorized by the recognized government in Luanda. SODIAM was created to provide a national mechanism for certification, regulation, sales, and exports. It thereby became a key part of Angola's attempt to channel diamond production into a controlled, internationally recognized system. SODIAM subsequently created the Angola Selling Corporation, or ASCORP, to concentrate the export of Angolan rough diamonds. SODIAM owned 51 percent of ASCORP, while the balance was principally held by Omega Diamonds and the Lev Leviev Group. ASCORP served as the exclusive export route for Angolan rough-diamond production for a period, and other exporters lost their licenses. ASCORP's license expired in 2004, after which SODIAM resumed direct responsibility for marketing and exporting the country's diamonds. Over time, SODIAM developed a broader institutional footprint. Its activities include the commercialization of diamonds produced through ENDIAMA-partnered mines as well as stones recovered by artisanal miners. The company also operates or supports sector infrastructure in Saurimo, including the Polo de Desenvolvimento Diamantífero de Saurimo, which is focused on logistics and supply-chain efficiency, and the Centro de Treinamento em Avaliação e Lapidação de Diamantes, which provides professional training in diamond assessment and cutting. International representation has included SODIAM Antwerp BVBA and offices or operations associated with Israel, Dubai, Shanghai, and Macau. The company became involved in the ownership structure surrounding the Swiss jewelry business De Grisogono. In 2017, SODIAM divested its shares, giving public-interest and legality as the stated reasons. Later reporting, particularly the International Consortium of Investigative Journalists' 2020 Luanda Leaks investigation, examined the relationship between De Grisogono, Sindika Dokolo, Isabel dos Santos, and Angolan state-linked diamond interests. The reporting alleged that politically connected individuals had benefited from diamond-related arrangements. These allegations form part of the public controversy surrounding the company and its former interests, although the supplied reference does not identify a conclusive judgment that SODIAM itself committed wrongdoing. In the 2020s, SODIAM continued to function as a central commercial and administrative institution in Angola's diamond industry. Its reported export volume reached 9.9 million carats of rough diamonds in 2023. The company's role consequently combines state oversight, export-channel management, market access, logistics, training, and the formalization of output from both industrial and artisanal sources.
