While comparing Amazonite and Elbaite 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 Elbaite chemical formula.
Another important criteria for qualitative analysis of gemstones is Amazonite and Elbaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amazonite and Elbaite Optical Properties during the identification of gemstone. Specific gravity of Amazonite is 2.90-3.10 whereas that of Elbaite is 2.90-3.10.
