Muscovite and Calcite Specific Gravity

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