Andalusite and Titanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andalusite and Titanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Titanite Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 3.48-3.60 whereas that of Titanite is 3.48-3.60.
