3" Lustrous, Translucent Sphalerite Crystal Cluster - Peru
This is a lustrous cluster of translucent, yellow sphalerite crystals that comes from Peru. Aggregations of white calcite/aragonite cover much of the sphalerite which all formed from a khaki siderite encrusted matrix. The entire specimen measures 3" wide and comes with an acrylic display stand.
Sphalerite is a part of the sulfide group and typically exhibits a grey/black appearance due to high concentrations of impurities. In its purest state, sphalerite's 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 since iron easily replaces zinc in the process of formation.
