Rosasite and Selenite (Ram's Horn) Association - Morocco #104170

This colorful specimen contains blue-green colored rosasite crystals, enshrouded in a thin layer of beautifully transparent selenite crystal. Along one edge of the specimen, selenite formations known as "Ram's Horn" can be found. Small spots of blue, likely azurite, can be found scattered across the exterior of the rock matrix. It comes with an acrylic display stand.

Rosasite is a secondary mineral that forms in oxidation zones of copper-zinc deposits, generally forming a fibrous botryoidal sphere that can appear vitreous and silky. While typically featuring a blue-green color, colorless specimens are not unheard of. The chemical formula of rosasite is CuZnCO3(OH)2.

Selenite is a variety of gypsum, a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4 · H2O). When chemically pure, gypsum is transparent and colorless, but impurities give the gypsum a diverse range of colors and formations. Desert rose selenite and satin spar are just a few of the varieties of gypsum known to have formed though hydrothermal processes.
