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