Several years later, additional samples were found by C. E. Adams in the nearby Dutoitspan mine and given to the MacGregor Museum in Kimberley.

[7] Shortly before 1932, the mineral was found about 100 miles (160 km) to the southeast of Kimberley at the Jagersfontein Mine in Orange River Colony.

[3] Earlier that year in his book The Genesis of the Diamond, Williams had called the mineral dutoitspanite, a name which was "apparently discarded".

[4] Bultfonteinite has been found in Australia, Botswana, Canada, Israel, Japan, Jordan, Russia, South Africa, and the United States.

[4] At the type locality, the mineral occurred in a large structure of dolerite and shale fragments in a kimberlite pipe.
