Thomsonite and Calcite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Thomsonite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thomsonite Vs Calcite during the identification of gemstone. Specific gravity of Thomsonite is whereas that of Calcite is .
