Nephrite and Hardystonite Chemical Formula
While comparing Nephrite and Hardystonite 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 Nephrite and Hardystonite chemical formula.

Nephrite and Hardystonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nephrite and Hardystonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nephrite and Hardystonite Optical Properties during the identification of gemstone. Specific gravity of Nephrite is 3.396-3.443 whereas that of Hardystonite is 3.396-3.443.
