This find literally redefines what you can ask for for the species Bultfonteinite, which usually occurs as a botryoidal aggregate (and then often covered by orlymanite) from the locality. THIS FIND, however, presents a significantly new habit for the species in the form of individual, acicular crystals to 7 or 8 mm in size. The white, acicular crystals liberally cover this large and attractive matrix plate which is also rich with small brown poldervaartite crystals.
