Pectolite and Gahnospinel Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pectolite and Gahnospinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Gahnospinel Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 3.65-4.55 whereas that of Gahnospinel is 3.65-4.55.
