3.2" Translucent Sphalerite Cluster on Calcite - Peru

This is a beautiful formation of translucent, yellow-green sphalerite crystals (resembling sphalerite var. cleiophane) on quartz. It comes from the Huaron Mining District in Peru and the entire specimen measures 3.2" long.

Comes with an acrylic display stand.

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.
