Calcite and Celestine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Calcite and Celestine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Calcite and Celestine Optical Properties during the identification of gemstone. Specific gravity of Calcite is 3.90-4.00 whereas that of Celestine is 3.90-4.00.
