Bultfonteinite (rare silicate) ex Rob Smith Coll.

Item Description

Bultfonteinite is a rare hydrated calcium silicate, with many of the finest examples coming from the famous mines of the Kalahari Manganese Field. This is an extremly rare and extremely rich, sculptural large crust covered with radial sprays of pearlescent needles of bultfonteinite crystals from the Wessels Mine. There are more crystals on the back, as a bonus. Top-flight, aesthetic and rare material from the Rob Smith Collection, as noted South African specialist.
