Bladed crystals of Covellite are clustered on edge in the classic form from Summitville, Colorado. On this piece the iridescent patina is similar to good specimens from Butte, but has the Colorado form. Crystals are distinct, well-separated and sharp, this is nearly pure Covellite just a few tiny bits of adhering matrix. Covellite is a somewhat common mineral but almost always massive. Crystallized Covellite is quite rare as there were only three locations that ever were good sources, at those sites it was still rare. Now all those mines are long gone.
