Dolomite and Albite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dolomite and Albite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dolomite and Albite Optical Properties during the identification of gemstone. Specific gravity of Dolomite is 2.60-2.65 whereas that of Albite is 2.60-2.65.
