Gaylussite and Pollucite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gaylussite and Pollucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gaylussite and Pollucite Optical Properties during the identification of gemstone. Specific gravity of Gaylussite is 2.86-2.94 whereas that of Pollucite is 2.86-2.94.
