Crystals of green Volborthite on both sides of matrix. Out of an old collection built in the 1970s-80s.

Chunky, thick groups of Hemimorphite crystals, complete all around and undamaged. Snow-white on one side and dusted with reddish Calcite crystals on the other.

Crystals of purple Axinite wtih Quartz crystals on one side and sparkling Albite crystals covering the backside. Fine and undamaged. Out of an old collection built in the 1970s-80s. From a famous find made in the spillway of the New Melones Reservoir.

Octahedral pink Fluorite crystal intergrown with a blade of Albite. It's really half an octahedron as the back side is smooth and flat. The back is fully crystallized (not a cleavage) and must have grown against another Albite blade. Out of an old collection built in the 1970s-80s. More pink, less yellow/orange than photos.

Heavy specimen of solid Copper and Cuprite from the historic Bisbee mining district. There are good vugs loaded with red cubes of Cuprite on both sides. Some of Cuprite crystals get good sized too, up to 4mm on edge.

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!!
