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

Nephrite and Zincite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nephrite and Zincite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nephrite and Zincite Optical Properties during the identification of gemstone. Specific gravity of Nephrite is 5.50-5.90 whereas that of Zincite is 5.50-5.90.
