Cyanotrichite, Brochantite
Two rare close cousins in one colorful specimen. Cyanotrichite (Hydrated Copper Aluminum Sulfate Hydroxide) typically forms acicular or hair like crystals aggregated into radial clusters, tufts and sprays - the form you see it in here if you look closely. It is aptly named since "cyano" and "trich" are derived from the Greek for blue and hair, respectively. It is formed from the oxidation of copper ore minerals along with other oxidation zone minerals. Here, it is paired with brochantite (Copper Sulfate Hydroxide) - it is the green, and the cyanotrichite is the blue. Ex. Mullane Collection.
