2.6" Fibrous Rosasite and Selenite Association - Mexico

This colorful specimen contains blue-green, fibrous rosasite crystals, collected from the Ojuela Mine in Durango, Mexico. The rosasite formed in fibrous spheres that resemble botryoidal masses, seemingly bubbling from the limonitic matrix. A selenite druze acted as the bed for the rosasites formation, leaving the superior half of the specimen with a beautiful glimmer.

What could be considered the base of this specimen, has been cut flat to allow for aesthetic display.

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.
