Anhydrite and Gaylussite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anhydrite and Gaylussite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Gaylussite Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 1.93-1.99 whereas that of Gaylussite is 1.93-1.99.
