This is a history of De Beers, the South African company that literally created and maintained the world diamond industry.The early history of the firm under Cecil Rhodes is a great story, as is the development of the modern De Beers and the worldwide cartel under the leadership of the Oppenheimer family.Much detail is provided about the firm, the mining and processing of diamonds, and the political struggles of De Beers.How the cartel actually worked as an economic unit deserved more detail.A reader today would want to know about the history of the firm in adapting to a post-apartheid world, but the book remains valuable for the history of De Beers.
