Diopside and Antigorite Specific Gravity

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