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

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