3.2" Lustrous, Translucent Sphalerite and Galena Association - Peru

This is a lustrous cluster of translucent, yellow sphalerite crystals from Peru. The sphalerite formed in association with cubic galena, over an aragonite encrusted matrix. The entire specimen measures 3.2" wide and comes with an acrylic display stand.

Galena is a lead based mineral that is in fact 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 lead content of the mineral.

Sphalerite is a part of the sulfides group and typically exhibits a grey/black appearance due to high concentrations of impurities. When sphalerite is in it's purest state, the chemical composition is ZnS, and can display a gemmy transparent light tan/yellow color. This is one of the few minerals that can form crystals ranging anywhere between gemmy and transparent to opaque and metallic-like. Opaque or cloudy sphalerite tends to be most abundant, due to the ease of iron replacing zinc in the process of formation.
