A cluster of sharp, bright rose-pink, opaque rhodochrosite crystals in a cleft on matrix. Individual rhodochrosite crystals reach about 5 mm across. The cleft is lined with colorless quartz crystals.  Scattered, mostly massive pyrite is also present. One sawn edge makes for a good display base.

Both sides of a nearly flat matrix have a rich coverage of opaque, velvety, chocolate brown siderite crystals. These crystals are flattened rhombohedra that reach about 2 mm across. No damage.

Fan-shaped sprays of translucent to opaque, yellow-brown adamites on a gossan matrix. Except for a few small contact points around the edges, the adamites are terminated. Individual sprays reach 5 mm or more. Bright green fluorescence under shortwave UV. Accented with a single, colorless, 4 mm calcite rhomb. No damage.

This specimen is dominated by a cluster of sharp, pearly dolomite crystals, accented with a bit of colorless quartz crystals and some tiny pyrites. The dolomites are opaque, very light pink, with individual crystals reaching 14 mm or more. The quartz points are terminated, reach 1.4 cm, and are mostly clustered along one side (last picture). The pyrite cubes are embedded in the massive quartz matrix, and reach 2 mm. This fine dolomite example displays quite nicely from several angles, and is free of damage.

From the classic Chinese realgar locality comes this cluster of glassy, colorless, mostly transparent calcite scalohedra on matrix. Individual crystals reach 4.9 cm. The largest calcites are doubly terminated. A bit of scattered edgewear is noted, insignificant at this price.

A colorless, mostly transparent calcite crystal, quite glassy, and accented with pyrite inclusions. The display faces of the calcite crystal are complete and undamaged, whereas the other half are cleavage faces. The included pyrite crystals are cubes and bars, and reach about 3 mm long. A somewhat obscure Wisconsin locality as well.

A colorless, translucent to opaque but crystalline quartz matrix is heavily included by tiny brown hubeite crystals. Also present are a few colorless apophyllite crystals to about 2 mm, and brassy pyrite cubes that reach about 7 mm. The Fengjiashan Mine is the type locality for hubeite, and this is a fine example (for the price) of this calcium-manganese-iron silicate, Ca₂Mn²⁺Fe³⁺[HSi₄O₁₃] ^. 2 H₂O. Some of the pyrites are incomplete, but otherwise the specimen is free of damage.

Glass, deep red, translucent to opaque proustite crystals and sprays scattered about on matrix. Individual crystals reach 4 mm. Quite nice under the hand lens, microscope, or camera lens. My camera was unable to capture the micro-beauty in this piece.

A thin, somewhat undulating matrix hosts a rich carpet of two descloizite generations. The first generation is a darker brown, and quite velvety. The second generation is tan, acicular, and puffy. No damage.

A large sphalerite specimen, with deep brown to black color, from the classic Tennessee locality. The pictures do not do justice to the true luster and brilliance of this piece. Also present near the base is a single, transparent and quite sharp 5 mm fluorite cube. The specimen sits quite nicely for display as shown without a stand. Might even be used as a bookend. No damage to this fine example.

A thin, flat plate of matrix hosts opaque, microcrystalline metatorbernite. Small mounds of a microcrystalline blue mineral (probably partially dehydrated chalcanthite) are also present. A good locality specimen.
