Sunstone and Fayalite Chemical Formula
While comparing Sunstone and Fayalite 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 Sunstone and Fayalite chemical formula.

Sunstone and Fayalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Fayalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Fayalite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 4.392 whereas that of Fayalite is 4.392.
