Sugilite and Sard Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sugilite and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Sard Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 2.58-2.63 whereas that of Sard is 2.58-2.63.
