Calcite and Girasol Specific Gravity

Another important criteria for qualitative analysis of gemstones is Calcite and Girasol Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Calcite and Girasol Optical Properties during the identification of gemstone. Specific gravity of Calcite is 1.98-2.50 whereas that of Girasol is 1.98-2.50.
