From: Goboboseb Mts, Brandberg Area, Erongo Region, NamibiaSize: 9.9 x 7.5 x 4.9cmWeight: 294g This is a truly unusual 4-in-1 mineral specimen! This single specimen has clear quartz with hematite inclusions, yellow calcite, and green prehnite. What a mix! At the bottom of the specimen is a fat quartz crystal which at one point in its life broke off, but the end appears to be partially self-healed. The specimen looks best when hit with a bright, directional light which really lights up all of the translucent minerals, especially the calcite and prehnite. Comes complete with the acrylic base.
