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

Nepheline and Crocoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nepheline and Crocoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Crocoite Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 5.90-6.10 whereas that of Crocoite is 5.90-6.10.
