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

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