In 1869, an even larger 83.50 carat diamond, known as The Star of South Africa, on the slopes of Colesberg Kopje on the farm Vooruitzigt belonging to De Beers brothers.

Within a month 800 claims were cut into the hillock was worked frantically by two to three thousand men. As the land was lowered so the hillock became a mine - in time, the world renowned Kimberley Mine.
