A second meeting of the Luanda Accord saw an expansion of those supporting the natural-diamond marketing collective, while others took steps to join the Natural Diamond Council (NDC).

The government of the Republic of Namibia became a signatory to the accord, created in June 2025. By joining, Namibia commits to supporting the natural-diamond industry through an agreed contribution to a global category-marketing fund, the NDC said Monday.

Many of the global industry’s leading players, including producing countries and organizations, have signed the accord, which the NDC will manage. The high-level meeting took place at the African Mining Indaba 2026 in Cape Town, South Africa.

“Natural diamonds have helped shape Namibia’s economic story for more than a century, creating jobs, supporting communities and contributing directly to national development,” said Honorable Modestus Amutse, Namibia’s minister of industries, mines and energy. “By joining the Luanda Accord, Namibia is affirming that producing countries have both a stake and a responsibility in telling the true story of natural diamonds. This is about ensuring that the value created by our resources continues to benefit our people, today and for generations to come.”

At the conference, the Gem and Jewellery Export Promotion Council (GJEPC) signed a memorandum of understanding (MoU) with the NDC, indicating their desire to work together in a “global push for natural-diamond marketing,” the GJEPC said. Meanwhile, the Dubai Multi Commodities Centre (DMCC) signed a letter of intent to join the council. Both organizations will become members of the NDC by May 1.

The moves follow last month’s announcement that Angolan state-owned companies Endiama and Sodiam, which also signed the accord, joined the NDC.
