Jadeite and Sapphire Chemical Formula
While comparing Jadeite and Sapphire 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 Jadeite and Sapphire chemical formula.

Jadeite and Sapphire Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jadeite and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jadeite and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Jadeite is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
