Esperite and Inderite Chemical Formula
While comparing Esperite and Inderite 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 Esperite and Inderite chemical formula.

Esperite and Inderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Esperite and Inderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Inderite Optical Properties during the identification of gemstone. Specific gravity of Esperite is 1.79 whereas that of Inderite is 1.79.
