This rare, dark-green copper chloride mineral is heavily dusted in a miroscopic crystal form over a thin crust of Chrysocolla on the host rock. Its dark-green color is its best field mark, and is so dark in this mossy mass as to appear almost black in some areas. Being a chloride, this mineral is very soluble in water, and being a copper mineral, it is poisonous, so it would be best to display such a piece behind glass, away from hungry organisms that don't know any better.
