Sphalerite

Sphalerite (Zn,Fe)S is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. When iron content is high it is an opaque black variety called marmatite. It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite. Miners have also been known to refer to sphalerite as zinc blende, black-jack, and ruby jack.

Sphalerite belongs to the isometric System. Its color is usually yellow, brown, or gray to gray-black. It can also be yellow, reddish, green, and less commonly white or colorless. Sphalerite may be shiny or dull. Its luster is adamantine, resinous to sub metallic in high iron varieties. It has a yellow or light brown streak and a Mohs hardness of 3.5–4. The pale yellow and red varieties have very little iron and are translucent. The darker, more opaque varieties contain more iron. Some specimens are also fluorescent in ultraviolet light.
