BROCHANTITE (Small cabinet)

Brochantite is a sulfate mineral classified among various cupric sulfates, with the chemical formula Cu4SO4(OH)6. It typically forms in arid environments or in areas where copper sulfide deposits undergo rapid oxidation. The mineral was named by Armand Lévy in honor of the French geologist and mineralogist A. J. M. Brochant de Villiers.

The crystals of brochantite exhibit a color range from emerald green to black-green and blue-green, and they can appear either acicular or prismatic. This mineral is frequently found in association with others such as malachite, azurite, and chrysocolla, and it may also create pseudomorphs with these associated minerals.
