Anhydrite and Pectolite Specific Gravity

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