Clinoclase is a copper arsenate mineral that forms small, well-formed crystals and masses in fractures and cavities. It typically occurs with a silky to adamantine lustre and can display a bottle-green to olive-brown color, sometimes with a faint blue-green hue in certain light. Habit ranges from tabular to prismatic and it is commonly found as granular aggregates in oxidized zones of copper-arsenate bearing rocks.

About Clinoclase

Notable specimens have come from historic copper mines and secondary deposits in the United States, United Kingdom, and Germany, with additional finds in Slovakia and Mali. Collectors value clinoclase for its rich color, crystal integrity, and the contrast it provides when paired with other copper minerals. Its relative rarity in high-quality crystals and its association with well-documented mineral localities add to its appeal for cabinet display and educational study.
