Stunningly attractive specimen of transparent Quartz with bright, brassy Chalcopyrite crystals. These are fairly common minerals, but in a combination and form to produce this beauty. Both minerals are evenly distributed and in good condition with just a few missing Quartz crystals. The Quartz are uniform in size and transparent. An overall very bright and showy specimen.

Individual spheres of yellow Prehnite grown in and around flat crystals of white Calcite. This is one of the most beautiful Merelani Prehnites I've ever seen. A fibrous blue Tanzanite and small white crystals (Laumontite?) are attached to the backside. A floater with no points of attachment and little to no damage.

Spherical, mound-shaped Prehnite with large, chunky crystals. This is a very good one in terms of form, size, color, and quality. Nearly pristine with just a couple minor nicked crystal tips.
