Gedrite and Amazonite Chemical Formula
While comparing Gedrite 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 Gedrite and Amazonite chemical formula.

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