Orthoclase and Pectolite Specific Gravity

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