Barney Barnato was a British Randlord and diamond magnate who was one of the entrepreneurs who gained control of diamond mining, and later, gold mining in South Africa from the 1870s up to World War I. He was known as a rival of Cecil Rhodes.

Kimberley is the capital and largest city of the Northern Cape province of South Africa. It is located approximately 110 km east of the confluence of the Vaal and Orange Rivers. The city has considerable historical significance due to its diamond mining past and the siege during the Second Anglo-Boer war. British businessmen Cecil Rhodes and Barney Barnato made their fortunes in Kimberley, and Rhodes established the De Beers diamond company in the early days of the mining town.
