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