Franklinite and Pectolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Franklinite and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Franklinite and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Franklinite is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
