Crocoite and Polyhalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Crocoite and Polyhalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Crocoite and Polyhalite Optical Properties during the identification of gemstone. Specific gravity of Crocoite is 2.78 whereas that of Polyhalite is 2.78.
