Foitite and Zircon Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Zircon Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Zircon Optical Properties during the identification of gemstone. Specific gravity of Foitite is 3.93-4.73 whereas that of Zircon is 3.93-4.73.
