Forsterite and Calcite Specific Gravity

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