Fayalite and Marialite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fayalite and Marialite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Marialite Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 2.50 whereas that of Marialite is 2.50.
