Pectolite and Powellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pectolite and Powellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Powellite Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 4.23 whereas that of Powellite is 4.23.
