Fayalite and Hexagonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fayalite and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
