They share the same chemical formula zns but have different crystal habits. Sphalerite s very low hardness 3 5 to 4 on the mohs scale and perfect cleavage make the mineral a very poor choice. Due to its lack of hardness it is called as a collector s gemstone. The gem quality material has a low iron content that makes it transparent crystals.
