Comment: This must be one of the most aesthetic specimens of Bultfonteinite and Poldervaartite combos I have seen. It is absolutely superb. The Bultfonteinite and Poldervaartite is found concentrated in the brecciated zones of the manganese ore. There are literally hundreds of sprays of white bultfonteinite amongst creamy colored elongated prisms of poldervaartite.
Minerals: Bultfonteinite (Ca2SiO2(OH,F)4) Poldervaartite ((Ca,Mn++)2SiO3(OH)2)
