In 2025, Angola exported 23,300 carats of polished diamonds, earning $109.7 million at an average price of $4,705.74 per carat—more than double the previous year’s volume and value, according to Sodiam.
Compared to the same period in 2024, export volumes rose by 126.5%, while export value increased by 107%. Although the average price per carat fell by 8.6% due to international market trends—such as rising demand for synthetic diamonds and an oversupply of natural polished diamonds—Sodiam stated that the achieved price still reflected the high quality of Angola’s products in terms of purity, size, and value.
A significant driver behind this growth was a sharp increase in exports from the Indian company KGK, which saw its quantity of exported polished diamonds jump by 176% in 2025. This contributed greatly to the overall rise in export volumes and revenues.
Domestically, Angola’s diamond processing sector also expanded. Local polishing factories purchased 62,500 carats of rough diamonds for processing, valued at around $104 million—a 67.6% increase in volume and a 69.6% increase in value compared to 2024.
These numbers indicate more dynamism within the local industry, although results varied across different factories, with some recording higher activity levels, while others saw more modest outcomes due to smaller production capacities.
Sodiam emphasized that diamond polishing is technically and financially complex, requiring specialized skills, precision, years of technical experience, and advanced financial and logistical management. The development of this segment needs significant capital to maintain stable operations, with each turnover cycle lasting three to five months, adding extra challenges to factory management.
Despite the difficulties caused by changes in the global diamond market, Sodiam highlighted that the 2025 results prove the resilience of Angola’s diamond sector. The performance of the polishing segment particularly shows the importance of ongoing investment in local benefaction to support value creation and long-term sustainability. Moreover, the incentive policies for Angola’s diamond polishing industry were central in maintaining activity and supporting both direct and indirect employment in the sector.
