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

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