Clinozoisite and Nepheline Chemical Formula
While comparing Clinozoisite and Nepheline 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 Clinozoisite and Nepheline chemical formula.

Clinozoisite and Nepheline Specific Gravity
Another important criteria for qualitative analysis of gemstones is Clinozoisite and Nepheline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinozoisite and Nepheline Optical Properties during the identification of gemstone. Specific gravity of Clinozoisite is 2.55-2.65 whereas that of Nepheline is 2.55-2.65.
