Sphalerite - Wikipedia

Sphalerite possesses perfect dodecahedral cleavage, having six cleavage planes. In pure form, it is a semiconductor, but transitions to a conductor as the iron content increases. It has a hardness of 3.5 to 4 on the Mohs scale of mineral hardness. It can be distinguished from similar minerals by its perfect cleavage, its distinc
