Russia is the volume leader with 37.3M carats, nearly 1.5× Botswana’s 25.1M carats.
Botswana punches above its weight: though producing 33% fewer carats than Russia, its output value almost matches Russia's due to higher value per carat price.
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.
