Mining in South Africa began with chance discovery of a diamond on the banks of the Orange River in 1867. By the 1880s, the mines around Kimberley produced around 95% of the world diamonds. In 1886, on the farm of Langlaagte, the rapidly growing diamond industry was eclipsed by the discovery of gold.
