Aurichalcite - Mineral Specimen crickets A lush rainforest canopy nowStriking, pale blue Aurichalcite specimen A secondary mineral in copper and zinc deposits, aurichalcite is typically found as blue or green crusts or mats of tiny acicular crystals, often as feathery, tufted, druzes; more rarely it is found as columnar crystal aggregates or crusts of either lamellar aggregates or as granular aggregates. This striking, pale blue example was excavated in the Atacama region of Chile. A perfect addition to a collection,
