The global supply of natural diamonds has already peaked, according to Moses Madondo, CEO of De Beers Group Managed Operations. Speaking at the Joburg Indaba, a major mining and resources conference in South Africa, he explained that production is on the decline, with several mine closures on the horizon and no significant new discoveries in sight.
Madondo highlighted that this limited supply could push diamond prices higher. “Since the turn of the century, we’ve only seen one major commercial discovery, the Luele mine in Angola, where we aim to start production by the 2030s. But on a broader scale, global diamond production is set to decline,” he said. This trend, while concerning from a supply perspective, offers the potential for price growth.
In the short term, Madondo expects production to dip, but he anticipates a recovery after 2025, driven by the Luele mine ramping up and South Africa’s Venetia mine shifting to underground operations. However, the looming closure of Canada’s Diavik mine in 2026 and the shutdown of several mines in Russia will further tighten supply.
