Sphalerite is a mineral composed of sulfide zinc. It is a natural compound, very common and one of the most important sources of zinc-sulfur. Sphalerite exhibits colors ranging from yellow to brown and red to black. It can also be transparent or opaque. It is usually opaque and has a glassy transparency in some varieties. It has a hardness of 3.5 to 4 on the Mohs scale and its chemical composition is ZnS (Zinc Sulfide). Sphalerite is mainly formed in sedimentary or hydrothermal rocks containing sulfur and zinc, at relatively low temperatures. Sphalerite is widely used as a collectible mineral and as a semi-precious stone used in jewelry. It is also used in light industry as a raw material for reflective glass, for catalysis and other industrial uses. It is also used as an abundant and inexpensive source of zinc, which is an essential metal for many organisms. Zinc is an essential mineral for life and is used in many industrial applications.
