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

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