While comparing Painite and Amazonite 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 Painite and Amazonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Painite and Amazonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Painite and Amazonite Optical Properties during the identification of gemstone. Specific gravity of Painite is 2.55-2.57 whereas that of Amazonite is 2.55-2.57.
