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