Exceedingly sharp, equant Cuprite crystal with a thin veneer of Malachite. This is a great crystal. There are a couple areas on back where you can see the deep red, glassy Cuprite. Ex. Carl Acosta collection.

Bright green Duftite over Mimetite. This may be a double psuedomorph as the Mimetite is in an unusual form and may itself be a psuedomorph. From the first oxidation zone dating back to the early 1900's. Small Duftite psuedomorphs after Azurite crystals adorn the right side.

Red Rhodochrosite crystals with flat pinacoidal habit covering angular chunks of Manganite breccia. The manganite beneath gives the illusion that the Rhodo have overgrown over another crystal species, but I believe it's simply manganite with an interesting angular form. Ex.Carl Acosta collection.

Single clear over pale green octahedron of Fluorite intergrown with Rhodochrosite, Quartz, and Calcite. The Fluorite has great luster and has small step faces modifying the main octahedral form. Super pretty and undamaged.

Superb Vesuvianite specimen composed of double-terminated crystals in a floater cluster. This is not your typical Vesuvianite and a real winner. Undamaged and rare form. 

Fine, double terminated Topaz crystal adorned with 4 psuedomorphs of Hematite after Garnet. Undamaged crystal from the Carl Acosta collection.

Cluster of unusually fine, double-terminated Prehnite crystals. Largest crystal is 1.8cm. Undamaged and a floater with no points of attachment. Ex. Will Henderson collection.

Cluster of sharply formed crystals of the rare psuedomorph of Tennantite after Azurite. Main crystal is 4.2cm tall with a sharp chisel termination. The crystal that slants behind the main crystal is missing it's termination, still, this is an impressive and rare piece from the now closed Tsumeb Mine. From the collection of noted Tsumeb collector Carl Acosta.

Classic Bisbee psuedomorph of Malachite after Azurite, and the Campbell Shaft produced the best from Bisbee. The crystal is exceptionally fine, double terminated, and on matrix - qualities that combine to make this a fantastic specimen. This was originally purchased from Al McGuinness in the 1970s and the old label has hand written on the back 'this is a good rock' indicating that this one stood out quality wise even back then.

Unusual Schorl specimen with a very steep pyramidal termination. I obtained this a few years ago in Tucson, awed by it's unusual form. Although I have looked, I've not seen another like it and do not know the locality. Complete and undamaged with bright glossy luster.

Complete and undamaged single crystal that at first glance looks like a typical Paprok crystal with it's pastel shades of pink and green. However, a closer look at the green zone reveals a band of bright yellow giving the crystal a brighter, different look with lots of visual pop.
