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

Esperite and Cinnabar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Esperite and Cinnabar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Cinnabar Optical Properties during the identification of gemstone. Specific gravity of Esperite is 2 whereas that of Cinnabar is 2.
