Zinc sulfide exists in two major crystalline forms, and this idealism is often a striking example of polymorphism. In either form, the geometry of the coordination is Zn and S tetrahedral. The more stable cubic form is also known as sphalerite and sphalerite.

The hexagonal form is known as a mineral wurtzite, but it can also synthetically.Zinc sulfide with the addition of a few ppm suitable activator is used as a phosphor in many applications of cathode ray tubes, are made to glow by X-ray screens in the dark products.

The transition from the sphalerite form to the wurtzite form occurs at about 1020 degrees Celsius. Tetragonal form is also known as mineral polhemusite very rare, familiar with the formula .
