Pyrope and Datolite Specific Gravity

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