Calcite and Adularia Specific Gravity
Another important criteria for qualitative analysis of gemstones is Calcite and Adularia Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Calcite and Adularia Optical Properties during the identification of gemstone. Specific gravity of Calcite is 2.54-2.61 whereas that of Adularia is 2.54-2.61.
