Rossmanite and Antigorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rossmanite and Antigorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rossmanite and Antigorite Optical Properties during the identification of gemstone. Specific gravity of Rossmanite is 2.58-2.80 whereas that of Antigorite is 2.58-2.80.
