While comparing Cavansite and Azurite 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 Cavansite and Azurite chemical formula.
Another important criteria for qualitative analysis of gemstones is Cavansite and Azurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Azurite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 3.70-3.90 whereas that of Azurite is 3.70-3.90.
