Fluorite With Chalcopyrite
Small Cabinet, 6.5 x 5.6 x 4.2 cm
Naica, Chihuahua, Mexico

Chalcopyrite, patinated green by oxidation, is the host for a spectacular, glassy and gemmy, octahedral crystal of fluorite, 2 cm in length, which is perched high on its matrix. The colorless fluorite crystal exhibits unusual growth on its crystal edges, and the faces appear to be slightly concave. In fact, the overall appearance of the fluorite is that of stepped growth, similar to the pyramids, but with some curves on closer inspection. The combination of fluorite on chalcopyrite is highly unusual from ANY locality
