Andalusite and Tektite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andalusite and Tektite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Tektite Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 2.34-2.51 whereas that of Tektite is 2.34-2.51.
