Beaconsfield is the name of a suburb of Kimberley, South Africa. It was formerly known as Du Toit's Pan. Du Toit's Pan was one of the earliest diamond mining camps. Du Toit's Pan is also the name of the main road extending southwards from the central business district of Kimberley, i.e. towards Beaconsfield.
Beaconsfield was a separate borough from Kimberley itself until its amalgamation with the latter as the City of Kimberley in 1912.
