This is a small thumbnail specimen but carries a load of colorful Franklin mineral species. It was hard to photo some of the species, but I think you will get the idea. The Zincite forms bright orange-red crystals. Tucked in several small crevices are colorless and bladed Chlorophoenicite to about 1mm and less. Gageite is seen as light brownish fibers, but are extremely small. The Pyrochroite is black and forms tiny crystals.
The specimen carries an old William Pinch label, which also states that it is out of the Trofimuck collection. You can see this under the provenance tab.
