Tetrahedrite, Chalcopyrite, Quartz
18-01 Pocket, Detroit City Portal, Sweet Home Mine, Alma, Park Co., Colorado, USA
10.4 X 13.3 X 5.8 cm
Calling all Colorado collectors! While obviously better-known for it’s world-class rhodochrosite, the Detroit City Portal/Sweet Home mine also produced what are probably the best tetrahedrite crystals from Colorado. This is a nice example, with large, crystals associated with chalcopyrite, quartz, and galena for a pleasing esoteric combo.
