Single Tourmaline crystal that grades up from medium green to clear to dark green at the termination. Unusual color zoning. Undamaged, with gem zones.

Cluster of smokey grey Quartz crystals. The prism faces of the large crystals are covered by smaller Quartz crystals and the termination faces are flat and smooth. There is also color zoning in the terminations with dark zones along the edges. Found in 2017.

Large open vug of blue Shattuckite over Dioptase. The Dioptase formerly covered larger Calcite crystals, which are now gone, only the tips of one or two crystals can be seen on the backside now, however their form is clearly evident from the inside of the vug. The specimen is almost entirely Dioptase and Shattuckite. An unusual feature of this specimen is the light, pearly luster on the surface of the Shattuckite, which is more typically a darker, matte luster. Rare and unusual.

Well formed, thick Wurtzite crystal, complete all around and undamaged. There is Graphite, Diopside, Pyrite, and a partial Tanzanite crystal attached to the surface. Stunning thumbnail.
