Anhydrite and Liddicoatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anhydrite and Liddicoatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Liddicoatite Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 3.02 whereas that of Liddicoatite is 3.02.
