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 Vs Calcite during the identification of gemstone. Specific gravity of Variscite is whereas that of Calcite is .
