Variscite and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Variscite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
