Sphalerite Mineral Specimen, Approx 1 inch

This raw sphalerite specimen measures approximately 1 inch (3cm) in length. Sphalerite is a sulfide mineral often mined for its zinc content, dark in color but reflective, and is often associated with other sulfide minerals such as pyrite and chalcopyrite. Sphalerite sometimes exhibits triboluminescence (glowing when fractured). Each sample arrives in a labeled and barcoded plastic bag. Suitable for mineralogy and economic geology classes, and general mineral identification exercises aligned with NGSS Evidence Statements.
