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