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

Cinnabar and Esperite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cinnabar and Esperite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cinnabar and Esperite Optical Properties during the identification of gemstone. Specific gravity of Cinnabar is 4.28-4.42 whereas that of Esperite is 4.28-4.42.
