A beautiful combination of white Baryte crystal rosettes evenly distributed on dark purple cube-shaped Fluorite crystals over yellow Fluorite. The specimen is in superb condition with no damage to any of the main crystals of either species. An American classic specimen.

A gemmy, complex Cassiterite crystal with glassy faces and overall smoky black color. A small bit of white matrix remains on the bottom, otherwise a floater. Excellent Chinese specimen, slight edge chipping otherwise undamaged. Good transparency. Ex. Debbie Meng's Minerals.

Terminated clear Quartz crystal with a light 'dusting' of small light green Chlorite balls and several light purple Fluorite crystals. The Fluorite crystal near the top is incomplete. Still an aesthetic combination of species from the locality. Ex. A. L. McGuinness Collection.

A flat plate of pink color scalenohedral Cobaltian Calcite crystals are host to a botryoidal mound of fibrous green Malachite crystals. Damage to a few of the Calcite crystals but without it you could add another zero to the price, at least. These are rare and those with the visual pop added by the Malachite are very rare.

A miniature size specimen of Enargite with several well-terminated silver-black crystals from Butte, Montana, known as 'The Richest Hill on Earth'. These mines have not produced for decades.

Deep purple, satin finish octahedral Fluorite crystals are seen intermixed with an earlier generation of green Fluorite crystals. These are New Mexico classics and the shown here is an exceptional example with no damage to the main crystals. Largest purple octahedral crystal is 2.1cm on edge.

Large glassy blue Topaz crystal complete all around with etched faces and water-clear transparency. The crystal detached in the pocket and is naturally etched all around. Weighs approximately 79 grams.

A plate of thin, dark color matrix hosts a cluster of clear, sharply terminated rhombohedral Calcite crystals and a small amount of green Duftite. An older Tsumeb classic with no damage to the Calcite crystals. Ex. Collection of Tom and Gale Parker. Excellent Tsumeb Calcite specimen.

Turquoise in matrix from historic Bisbee, Arizona. The Turquoise was located in the conglomerate rock atop the main Copper ore deposits that was removed as overburden. Most the Bisbee Turquoise was therefore recovered in the mine dumps in the 1950s and 1960s and are now uncommon. The specimen comes mounted in an old 2 inch x 2 inch plastic box with label. It has one sawn flat surface to show the sky-blue Turquoise.
