Fayalite and Scheelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fayalite and Scheelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Scheelite Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 5.9-6.3 whereas that of Scheelite is 5.9-6.3.
