The village resides at the confluence of the Harts and Vaal rivers. It developed from a diamond-diggers’ camp and is said to have given the name after the first person to find diamonds there. The public diggings were proclaimed in November 1871, a village management board was instituted in 1931, and municipal status attained in 1970.
