Pectolite and Franklinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pectolite and Franklinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Franklinite Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 5.05-5.22 whereas that of Franklinite is 5.05-5.22.
