A striking specimen featuring Native Silver on white Calcite. The Calcite has been etched revealing the beautiful, dendritic formations of the Native Silver (Dendrite: a crystal aggregate composed of branching skeletal or tree-like formations. Minerals.net). The crystal formations are stunning, and this piece is...

This is a massive cluster of countless intersecting, doubly-terminated prismatic Epidote crystals (ok, maybe not countless, but way more than I care to count . . . ). The crystals have striated faces, a deep green color and are in excellent condition. There is...

A large cluster of pink, mangano intersecting bladed Calcite crystals with large, lustrous, clear Quartz crystals, all in a large, protected vug. The highlight of this piece is a very large, perfectly centered Calcite blade rising above the rest of the blades along with...

A very large Geode lined with beige Heulandite crystals hosting several intersecting sprays of lustrous, colorless, highly translucent, acicular (needle-like) Scolecite crystals. Simply an amazing piece - the crystal formation, the luster, the contrast, the symmetry - it’s all outstanding. And being protected within...

This specimen hosts a cluster of lavender Calcite scalenohedra on a layer of slightly amethystine crystalline Quartz. It’s unusual to see a specimen with such contrasting halves - the large, lavender Calcite crystals across from the crystalline Quartz - like a line was drawn...

The luster, the color contrast and the symmetry are all outstanding. A beautiful specimen in excellent condition. Location: Daye Mine, Hubei...

This is a huge, stunning specimen of etched Goshenite on Albite with Muscovite. Goshenite is colorless, void of any trace impurities - the purest form of Beryl (the same mineral family of Aquamarine and Emerald). The clarity, the size,  the natural hydrothermal etching, the...

This piece is exceptional. It features a large (2.7 cm), lustrous, transparent complex Calcite crystal, a pair of translucent, peach-colored intersecting Stilbite crystals, and numerous, gemmy, colorless, doubly-terminated Apophyllite crystals, all set on a matrix of black, stalactitic Chalcedony. It’s just an amazing piece...

A large, beautiful and lustrous specimen of Jacaré Smoky Quartz. The crystals are well formed, transparent and have a rich “smoky” color with darker crystal terminations and outer edges. The crystals are aligned in a unique, parallel orientation which is what gives this particular...

This is a huge, incredible plate of Vanadinite. I have not seen a larger nor nicer specimen. The hexagonal crystals are deep red, translucent and gemmy with a glassy luster. The contrast is perfect between the deep red and the light colored matrix. It...
