Azurite and Chromite Chemical Formula
While comparing Azurite and Chromite 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 Chromite chemical formula.

Azurite and Chromite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Azurite and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Azurite and Chromite Optical Properties during the identification of gemstone. Specific gravity of Azurite is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
