Dolomite and Pezzottaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dolomite and Pezzottaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dolomite and Pezzottaite Optical Properties during the identification of gemstone. Specific gravity of Dolomite is 2.90-3.14 whereas that of Pezzottaite is 2.90-3.14.
