Beautiful Illinois Fluorite specimen with stepped cubic faces on the front and etched surfaces on the backside. Translucent deep purple color with a bright blue outer layer. Small Calcite crystals are attached to the backside.

Aesthetic cluster of large, elongated Dioptase crystals. Undamaged. This is from the Lou Schwartz collection and one of the earlier pieces found at the locality.

Large, elongated single Dioptase crystal. Undamaged, transparent to translucent with attached white Calcite around the base. Exceptional single thumbnail Dioptase.

Well isolated Dioptase crystals to 8mm on white rhombic Calcite crystals. There is a second generation of Plancheite (?) or possibly tiny Calcite atop the Dioptase crystals. The label indicates that the mineral on the Dioptase is Plancheite.

Large, dark green but transparent single Tourmaline crystal from recent production at the famous St. Anne's mine in Zimbabwe. Tourmaline has been very rare from this mine historically, which has primarily targeted blue Topaz. Most Tourmaline found here occur as small pencil-like crystals and this large crystal in an anomaly. Though dark, it is transparent facet grade green throughout with a more greenish brown color at the termination. There is a bit of edge chipping along one side, otherwise it's complete all around and perfect. Weighs a hefty 50.8 grams.

Bright yellow crystals of Sulfur attached and fully included within transparent Gypsum var. Selenite. Sulfur inclusions in Selenite are uncommon and this is an excellent example. See the current issue of Mineralogical Record for an article on this locality.
