Angola’s Polished Diamond Exports Jump 127% in 2025 Amid Challenging Market Conditions
According to Sodiam, Angola’s state-owned diamond marketing and sales body, the country exported 23,300 carats of polished diamonds during the year, marking a 127% increase over 2024. Export revenues also rose sharply, climbing 107% to $109.7 million.
However, the average price per carat declined by 9% to $4,706, reflecting challenging global conditions driven by rising demand for synthetic diamonds and an oversupply of natural polished stones.
A significant contributor to the overall performance was a 176% surge in polished-diamond exports from Indian major KGK’s manufacturing facility in Angola, which provided a notable boost to both volumes and value.
Commenting on the performance, Sodiam highlighted that despite global market shifts, the 2025 results underline the resilience of Angola’s diamond sector. The company also reiterated the importance of strengthening local beneficiation as a key strategy to enhance value creation and ensure long-term sustainability of the industry
