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!!

Chrysocolla after Hemimorphite crystals all over a matrix comprised primarily of massive Chrysocolla. A colorful and somewhat common replacement at the 79 Mine. Older specimen dating back to about the 1970s.

Bright orange, transparent Wulfenite crystals over a druse of bubbly Mimetite. The Mimetite is yellow on the left side of the specimen and orange colored on the right side. A small amount of Chrysocolla lies beneath the Mimetite.

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!

Translucent yellow cubes of Fluorite associated with white Dolomite crystals. Micro Pyrite crystals cover some of the Fluorite crystals and a good portion of the backside.

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, reticulated group of Cerussite crystals. This is an older piece, larger and more robust than typical.

Mass of crystallized Copper with attached, distinct crystals of Cuprite. Comes with an old Roberts Minerals label.
