Eight of the top 10 producers are African (Botswana, Angola, DR Congo, South Africa, Zimbabwe, Namibia, Sierra Leone, Lesotho).
Low-volume producers like Namibia (2.4M ct → $1.2B) highlight how smaller deposits can yield high-value diamonds.
The United Arab Emirates tops the list with immigrants making up 88% of its total population.
Qatar follows closely with 87% of its residents being immigrants.
