Foitite and Kunzite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Kunzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Kunzite Optical Properties during the identification of gemstone. Specific gravity of Foitite is 3.15-3.21 whereas that of Kunzite is 3.15-3.21.
