Foitite and Amber Specific Gravity

Another important criteria for qualitative analysis of gemstones is Foitite and Amber Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Foitite and Amber Optical Properties during the identification of gemstone. Specific gravity of Foitite is 1.05-1.10 whereas that of Amber is 1.05-1.10.
