White Cerrusite snowflake, or rather 'snow ball' due to it's rounded shape of multiple intergrown snowflakes. From Tsumeb and recently released out of an old collection built in the 1970s-80s.

Cluster of rhombic and lenticular Calcite crystals heavily included with green Mottramite that also protrudes out the Calcite. Good all around. One of my favorite types of Tsumeb specimens. Comes with an old Lesnicks label.

Heavy metallic matrix filled with Olivenite crystal lined vugs. Small spheres of Malachite are present on the Olivenite crystals. Comes with an old Mathiasen Minerals label.

Three yellow Calcite crystals with Galena crystals on matrix covered by small Dolomite crystals. This is an example of how exceptional aesthetics turn a common mineral into a fine mineral specimen. The top crystal is double-terminated and each of the two Calcite on the left side have Galena crystals at their bases. Complete all around and undamaged and good when viewed from any angle. A floater with no points of attachment. A good one!!

Showy miniature sized specimen of transparent cubes of Fluorite atop Sphalerite with a small amount of white Calcite crystals accenting the lower left. The Fluorite cluster is 2cm in size. Very nice piece!

Stalactitic formation of yellow/orange Calcite sprinkled with Galena crystals. Both ends are broken showing the Calcite crystals structure.

Old Mexican Mimetite specimen with particularly bright yellow coloration.

Thick, wavy sheets and masses of Copper. Specimen is almost entirely Copper with a bit of rock matrix mixed with Copper at the base.
