Andradite and Halite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andradite and Halite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Halite Optical Properties during the identification of gemstone. Specific gravity of Andradite is 2.17 whereas that of Halite is 2.17.
