Eureka Diamond

The Eureka Diamond was the first diamond discovered in South Africa. It weighed 21.25 carats (4.250 g), and was found near Hopetown on the Orange River in 1867. The diamond, cut to a 10.73-carat (2.146 g) cushion-shaped brilliant, is currently on display at the Mine Museum in Kimberley. The discovery of diamonds in South Africa led to the Kimberley Diamond Rush, and marked the beginning of the Mineral Revolution.
