Poldervaartite With Calcite
N'Chwaning Mine, Kalahari Manganese Fields, South Africa
Small Cabinet, 6.1 x 4.1 x 2.5 cm
A really unusual specimen with both the red crystal and the beige spherical aggregate styles both on the same specimen in close contact, all accented by a few sparkly calcite crystals. Really wild combination! The lump you see in the center of the polder ball is a calcite crystal, and then next to it a slight gap int eh crystal coverage of the sphere. In person, that little dimple isn't as obvious because you tilt the specimen back for display instead of straight up as shown. Overall, though, this is a very cute combination piece and the juxtaposition of crystal forms of the same mineral on one piece is interesting.
