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

Nepheline and Aegirine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nepheline and Aegirine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Aegirine Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 3.50-3.60 whereas that of Aegirine is 3.50-3.60.
