Brochantite

Brochantite is a vivid green copper sulphate hydroxide mineral, recognized for its emerald-green coloration and distinctive crystal formations. Commonly occurring as a secondary mineral in oxidized copper deposits, it forms through the alteration of primary copper-bearing minerals. Brochantite typically develops as slender prismatic to acicular crystals, often occurring in radiating aggregates, drusy crusts, and granular masses. Its rich green colour and varied crystal habits make it an attractive mineral among collectors. Explore our selection of genuine brochantite specimens for your collection.
