2.25" Rosasite, Selenite and Ferroan Dolomite Association - Morocco
This colorful specimen contains blue-green colored rosasite crystals on a bed of dark reddish brown ferroan dolomite. Small translucent selenite crystals can be found atop the dolomite as well as enshrouding the rosasite crystal formations. Galena is found in a cluster on one side.
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.
Galena is a lead-based mineral and the primary ore of lead, and has been used for its lead content for thousands of years. Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS.
While galena will not pose a health hazard by sitting on the shelf or even from casual handling, we suggest washing hands following handling due to the mineral's lead content.
