1.75" Rosasite, Selenite, and Malachite on Ferroan Dolomite - Morocco

This colorful specimen contains small clusters of bright blue-green rosasite interspersed with transparent selenite and deeper green fibrous malachite on a bed of dark purplish ferroan dolomite. Galena can be found embedded in the matrix.

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.
