Liddicoatite and Leucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Liddicoatite and Leucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Liddicoatite and Leucite Optical Properties during the identification of gemstone. Specific gravity of Liddicoatite is 2.45-2.50 whereas that of Leucite is 2.45-2.50.
