Freetown, Sierra Leone: Against a backdrop of mounting concern over the future of Africa’s diamond sector, ministers from leading diamond-producing nations convened in Freetown, Sierra Leone, on May 20, 2026, to address a challenge that is rapidly transforming the global jewellery landscape—the growing dominance of laboratory-grown diamonds.
A key voice at the Council of Ministers meeting of the African Diamond Producing Association (ADPA) was Tanzania’s Deputy Minister of Mines, Dr. Steven Kiruswa, who issued a strong call for collective African action to safeguard the continent’s natural diamond industry.
“We are at a tipping point,” Dr. Kiruswa told delegates. “The proliferation of lab-grown diamonds is steadily eroding the value, credibility and livelihoods associated with natural diamonds. Unless we act together, we risk compromising one of Africa’s most valuable strategic resources.”
His remarks reflected the broader sentiment of a gathering marked by both concern and resolve. For many African nations, diamonds are far more than luxury products; they represent a vital source of government revenue, support thousands of artisanal mining jobs, and play a significant role in funding infrastructure, education and community development initiatives.
However, the rapid expansion of synthetic diamonds—created in laboratories yet virtually identical in composition to natural stones—has introduced new challenges for the industry. Stakeholders fear that growing consumer confusion between natural and lab-grown diamonds could weaken the premium status and emotional value long associated with mined diamonds.
Delegates stressed that without stronger regulatory frameworks, more robust certification systems and unified industry messaging, consumer confidence in natural diamonds could gradually diminish.
Dr. Kiruswa urged African producers to adopt a coordinated continental strategy built around three key priorities: strengthening international certification standards, launching global marketing initiatives that emphasize the rarity, origin and heritage of natural diamonds, and increasing local value addition through cutting, polishing and jewellery manufacturing within Africa.
“If consumers cannot clearly distinguish natural diamonds from synthetic alternatives, the long-term value of our resources will inevitably be affected,” he warned. “Africa must protect not only its mineral wealth but also the trust and confidence that underpin it.”
The proposal received strong support from ministers attending the summit. Several delegates argued that Africa must move beyond its traditional role as a supplier of rough diamonds and secure a greater share of the value chain by expanding domestic processing, manufacturing and branding capabilities.
