While comparing Amazonite and Pezzottaite 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 Amazonite and Pezzottaite chemical formula.
Another important criteria for qualitative analysis of gemstones is Amazonite and Pezzottaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amazonite and Pezzottaite Optical Properties during the identification of gemstone. Specific gravity of Amazonite is 2.90-3.14 whereas that of Pezzottaite is 2.90-3.14.
