Sapphire and Dolomite Specific Gravity

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