Fayalite and Shigaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fayalite and Shigaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Shigaite Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 2.32 whereas that of Shigaite is 2.32.
