Aurichalcite

This aurichalcite formed in the oxidized zone of a copper- and zinc-rich deposit, where mineral-laden waters deposited delicate, fibrous blue-green crystals along open surfaces in the host rock. The Ojuela Mine is a classic Mexican locality, famed for its intricate secondary minerals and vibrant crystal forms.

Light, silky, and visually striking, this specimen reflects the subtle chemical processes that occur near the Earth’s surface and showcases the rich mineral diversity that has made Ojuela a favorite among collectors.
