Enstatite and Dolomite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Enstatite and Dolomite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Enstatite and Dolomite Optical Properties during the identification of gemstone. Specific gravity of Enstatite is 2.80-2.95 whereas that of Dolomite is 2.80-2.95.
