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