A group of lustrous, slightly iridescent, opaque and brown sphalerite crystals sits on a bit of chert matrix. Individual sphalerite crystals reach 9 cm across. Accenting the sphalerite faces is a sprinkling of small, bright chalcopyrite tetrahedra. Across the bottom of half of the specimen (including the matrix) is a dusting of colorless, small but sharp quartz crystals. This aesthetic piece sits well for display at several angles without needing a stand. A little scattered edgewear (which does not distract), otherwise free of damage.

A cluster of dark fluorite cubes with naturally rough surfaces. When strongly backlight, the specimen shows deep blue and purple colors. The roughness on the crystal faces is a combination of small growth features and some natural pitting. The largest individual fluorite cube measures 2.7 cm along the edge. Except for the usual cleaves and breaks along the base where removed from matrix the specimen has no damage. Sits well for display as shown without the need for a stand.

A glassy and lustrous, opaque schorl crystal rises 4 cm above a crystalline microcline matrix. The termination is nearly undamaged, save a few small chips where some adhering microcline flaked off.

Sprays of opaque pectolite needles rise from a prehnite/basalt matrix. The pectolite carpet is about 6 mm thick, and is topped with a pinkish layer of tiny terminations. Nice for the species and locality, and free of damage. Sits well for display as shown without need for a stand. The Millington Quarry is now closed, and being reclaimed for development as a housing complex.

Deep red-brown, resinous sphalerite crystals intergrown with brassy (but tarnished) chalcopyrite tetrahedra. The chalcopyrites reach about 5 mm, and some are incomplete. A patch on the back is decorated with 2 mm deep red and nearly transparent 'ruby jack' sphalerite crystals. The specimen is notable among Picher Field material for the intergrowth of the two sulfide species that are present; more commonly these specimens consist of chalcopyrite crystals on top of sphalerite.

Square, greenish-yellow tabular autunite crystals lie on, and rise up from, a flat matrix. Individual crystals reach 2 mm. Bright green fluorescence under both longwave and shortwave UV. An excellent example of the species in miniature, and free of damage. Looks like this would be a fun one to explore under the hand lens, microscope lens, or camera lens.

A rounded, elongated calcite crystal, heavily included with sand. A great example in miniature of this interesting phenomenon. No damage.

A light yellow, transparent to translucent fluorite crystal, partially coated on one face with colorless, complexly-crystalline and mostly transparent calcite. Also present on this fluorite face are patches of dull black, bubbly bitumen crust. In the last photo we can see that under longwave UV, the calcite exhibits while fluorescence (probably due to hydrocarbon inclusions). Overall the fluorite is a bit rough, but the main interest here is the association and fluorescence.

Half of an agate geode, with a good polish on the cut face, and a small hollow area lined with quartz crystals at the center. No damage.

A cluster of thin, translucent to opaque, light golden-yellow muscovite crystals, in the classic 'star' formation. A few bent tips (typical for muscovite). An affordable example of this interesting muscovite crystal habit.

An opaque tourmaline crystal, probably a very dark blue indicolite. A single crystal with two shafts, separated by a cleft. Each shaft has its own termination. A few small chips and contacts on this locality specimen.

A lightly smoky quartz crystal, shot through with tourmaline needles, on a scrap of albite/microcline matrix. The quartz crystal is complete, with some stepped growth areas due to growth interference or healed breaks. The tourmaline is black and opaque, except for the 1.7 cm, terminated tourmaline crystal that lies across the quartz termination; this tourmaline has a blue-green termination. No significant damage to this specimen which is very typical of the locality.
