Leucite and Franklinite Specific Gravity

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