Pietersite and Epidote Chemical Formula
While comparing Pietersite and Epidote 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 Pietersite and Epidote chemical formula.

Pietersite and Epidote Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pietersite and Epidote Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pietersite and Epidote Optical Properties during the identification of gemstone. Specific gravity of Pietersite is 3.25-3.50 whereas that of Epidote is 3.25-3.50.
