- Sphalerite, Chalcopyrite, Galena
- Commodore Mine, Amethyst Vein, Creede District, Mineral Co., Colorado, USA
- Small Cabinet, 7.3 x 5.9 x 2.1 cm
A fine combination plate with very gemmy, golden-yellow sphalerite crystals, brassy chalcopyrite crystals and a rich scattering of fortification to hoppered galena crystals from the small find a few years ago at the Commodore Mine at Creede, Colorado. Many of the highly lustrous, black-looking sphalerite crystals are, in fact, partially gemmy. The largest gemmy sphalerite crystal is 1.3 cm. These caused a major stir at the Tucson Show, when they came out. Ex. George Fisher and Mijer Collections.
