Dolomite and Kainite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dolomite and Kainite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dolomite and Kainite Optical Properties during the identification of gemstone. Specific gravity of Dolomite is 2.15 whereas that of Kainite is 2.15.
