Gypsum and Datolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gypsum and Datolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gypsum and Datolite Optical Properties during the identification of gemstone. Specific gravity of Gypsum is 2.90-3.00 whereas that of Datolite is 2.90-3.00.
