Jan 15, 2021 Sphalerite, (Zn,Fe)S, has an impurity of iron in it, which substitutes for zinc in the structure. The concentration of iron in these substitutional sites affects the colour of the mineral. Pure ZnS is colourless, and in powdered for, white. At low concentrations of iron, sphalerite is known as cleiophane, and is yellow or greenish

Sphalerite is a polymorph with two minerals, wurtzite and matraite . The three are called polymorphs (meaning many shapes) because although they have the same chemistry, (Zn, Fe)S or zinc iron sulfide, they have different structures and therefore different shapes.
