Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities? After each set of pictures there should be some descriptive text. If none appears it means that we need someone to tell us about the specimens from that locality and something about the geology of the occurrence.
Covellite
CuS Hexagonal
Good crystals of covellite are rare. In most locations, covellite is a massive material. Crystals have been found at the Calabona mine, Italy, Summitville, Colorado and Butte, Montana.
Covellite is normally found in the sugergene enriched sulfide zone of copper deposits. It is rarely found as tiny crystals from volcanic fumaroles.
Italy, Sardinia, Calabona Mine
Most covellite specimens were produced prior to the 1850's.
