04991 - Well Crystallized Acicular Brochantite with Quartz from South Morocco Morocco The matrix and the cephalonBrochantite is a sulfate mineral, one of a number of cupric sulfates. Its chemical formula is Cu4SO4(OH)6. Formed in arid climates or in rapidly oxidizing copper sulfide deposits. Crystals of brochantite can range from emerald green to black green to blue green, and can be acicular or prismatic. Brochantite is often associated with minerals such as malachite, azurite, and chrysocolla, and may form pseudomorphs with these minerals. Brochantite is a
