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

Epidote and Andesine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Epidote and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Epidote and Andesine Optical Properties during the identification of gemstone. Specific gravity of Epidote is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
