The black color of this sphalerite sample indicates a high iron content. Sphalerite is a mineral that consists largely of zinc sulfide in crystalline form, but it almost always contains variable amounts of iron. Its chemical formula may therefore be written as (Zn,Fe)S. Its color is usually yellow, brown, or gray to gray-black, and it may be ... Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear to white crystals (known as Cleiophane ). Yellow to orange sphalerite is often called "golden sphalerite."

As iron content increases, sphalerite forms dark ...Sphalerite: Galena and sphalerite commonly occur together and darker varieties of sphalerite may initially be confused with galena. Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two.
