Andalusite and Tinzenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andalusite and Tinzenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Tinzenite Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 3.355-3.433 whereas that of Tinzenite is 3.355-3.433.
