Sphalerite

Sphalerite is the primary ore of zinc, recognized for its brilliant luster and wide range of colors, from yellow and red to brown and black. It crystallizes in the cubic zincblende structure, closely related to diamond, and has a Mohs hardness of 3.5–4. Sphalerite often contains impurities such as iron, cadmium, and manganese, which influence its color and properties.

Collectors and mineralogists prize sphalerite for its perfect cleavage, high refractive index, and sometimes striking transparency. Its presence in ore deposits provides valuable information about geological conditions and mineral formation. If you’re interested in minerals that are both industrially significant and visually captivating, sphalerite is a mineral to explore.
