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.

Vuggy white Dolomite matrix with areas of Dolomite crystals loaded with yellow Wulfenite crystals. The Wulfenite crystals reach 1cm in size, are translucent, and are slightly dipyramidal. Comes with an old Roberts Minerals label, who were well known for fine minerals. Please excuse the (now gone) pine needle.

Thick, orange wulfenite crystals to 1cm that contrast well against the white matrix.

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!!

Cluster of yellow Quartz variety Citrine. This is old material from Brazil and has the most true yellow color of any Quartz I've ever had. Most Citrine is a shade of orangey brown - there is no orange color in this one. Undamaged and pristine.

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.
