Bultfonteinite, Poldervaartite
N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa
Large Cabinet, 24.0 x 12.2 x 7.4 cm
This was the largest and best specimen I have yet seen from a small find of earlier this fall, at the N'Chwaning. 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. The piece is significant for both quality and size. 24.0 x 12.2 x 7.4 cm
