Dioptase and Ekanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dioptase and Ekanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Ekanite Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 3.28-3.32 whereas that of Ekanite is 3.28-3.32.
