Sphalerite and Sard Chemical Formula
While comparing Sphalerite and Sard physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Sphalerite and Sard chemical formula.

Sphalerite and Sard Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sphalerite and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphalerite and Sard Optical Properties during the identification of gemstone. Specific gravity of Sphalerite is 2.58-2.63 whereas that of Sard is 2.58-2.63.
