Located on Dorstfontein farm.
A diamond mine in a kimberlite pipe, owned by the De Beers and closed in 2005. The deepest mining level was 870 meters below the surface.
In 1974, a miner at Dutoitspan picked up an octahedral diamond of 616 ct. This crystal is the largest diamond ever found in all the Kimberley mines, and also the largest ever octahedral diamond that has been recovered.
Note: The Du Toits Pan is a water-filled pan just south of the mine, from which diamonds were recovered in the 19th century.
