For decades, Angola's place in the global diamond industry was defined largely by its geological potential. Today, the country is attempting something more ambitious: repositioning itself not only as a major producer of natural diamonds, but as a model for how diamond resources can be translated into economic development, traceable supply chains and local manufacturing.
That ambition was on full display at the Angola Diamond Convention 2026, where government representatives, mining executives, manufacturers and retailers gathered around a common message. Angola no longer wants to be viewed solely through the lens of production volumes. Instead, it wants the industry to evaluate its diamonds through a broader measure of impact.
The concept was articulated by Priscilla, Director of Social Responsibility at Indiama, who introduced what became one of the convention's defining themes: the "Fifth C."
For generations, diamonds have been valued according to Cut, Clarity, Colour and Carat. Angola is proposing a fifth consideration — Community.
Diamonds cannot exist disconnected from people. Did this stone create opportunity? Support education? Create dignity?Priscilla, Director of Social Responsibility, Indiama
The idea reflects a broader effort by Angola to connect diamond revenues directly to visible social and economic outcomes. Across mining regions, revenues are being channelled into schools, healthcare facilities, training centres, roads and higher education infrastructure. Among the projects highlighted during the convention was a university funded through Sodiam that is expected to accommodate 10,000 students.
The message was clear: the industry should increasingly assess not only where a diamond came from, but what it helped create.
The convention also highlighted Angola's growing strategic importance within the global natural diamond supply chain.
According to Miguel Vemba, Director of Operations and Joint Ventures at Indiama, Angola's production has increased from 7 million carats in 2017 to 14 million carats in 2024. The country is targeting 50 million carats by 2025.
These figures take on added significance against a backdrop of declining global rough supply. The closure of Australia's Argyle mine removed approximately 14 million carats from the market, while Canada's Diavik mine is nearing the end of its productive life. Global diamond production has fallen below 100 million carats annually for the first time in more than a decade.
As traditional sources contract, Angola is positioning itself as one of the few major growth stories in natural diamonds.
Angola's ambitions extend beyond extraction.
One of the convention's most discussed examples was KGK Group's manufacturing operation in Saurimo. After entering Angola in 2019, the Indian diamond manufacturer established two facilities that now employ close to 500 people, with 70-75% of employees being Angolan nationals trained by the company. The operation currently processes 10,000-11,000 carats per month and plans to double capacity within two years.
The project reflects Angola's broader push toward beneficiation—retaining more value within the country rather than exporting rough production alone.
Another recurring theme throughout the convention was traceability.
Angola reported that approximately 90% of its diamond production can be traced directly to the mine of origin, a distinction that is becoming increasingly important as retailers and consumers demand greater transparency.
That traceability story has already begun resonating downstream.
Alison Charlo, Vice President of Responsible Sourcing at Brilliant Earth, described how improved access to certifications, provenance data and blockchain-backed documentation enabled the retailer to launch its "Pathway to Beyond Conflict Free Diamonds" collection featuring Angolan-origin diamonds at JCK 2025.
Perhaps her most significant observation was that consumers responded positively not because the story was perfect, but because it was transparent.
The Angola Diamond Convention was ultimately less about carats than about narrative.
For years, conversations around natural diamonds have focused on scarcity, competition from laboratory-grown diamonds and supply constraints. Angola's message was different. The country's leadership argued that the future value proposition of natural diamonds will increasingly depend on their ability to demonstrate provenance, economic contribution and community impact.
Whether the industry ultimately embraces the idea of a Fifth C remains to be seen. But Angola has made its position clear: the next chapter of the natural diamond story should be measured not only by what comes out of the ground, but by what remains behind after the mining is done.
