Leucite and Nosean Specific Gravity

Another important criteria for qualitative analysis of gemstones is Leucite and Nosean Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Leucite and Nosean Optical Properties during the identification of gemstone. Specific gravity of Leucite is 2.30-2.40 whereas that of Nosean is 2.30-2.40.
