This is a history of the production and marketing of diamonds from the period of the "rush" to Kimberley and the rise of de Beers until the formation of the central Selling Organization by South African producers and London and South African merchants. Based on a wide variety of original sources from public and mining company archives, it is a study of both the politics and business of a South African monopoly which became an international cartel.
