Angola
With over 7 million carats per year, Angola has proved to be one of the most reliable diamond-producing countries in Africa. Much of its diamond reserves are located in Lunda Norte and Lunda Sul provinces. Although Angola has a number of diamond mines, its largest and most important mine is Catoca, which is world’s fourth-largest diamond mine. The country also has several sedimentary mines operated by artisan miners, key among them being the Somiluana mine.
