Enstatite and Sugilite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Enstatite and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Enstatite and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Enstatite is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
