Ekanite and Star Sapphire Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ekanite and Star Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ekanite and Star Sapphire Optical Properties during the identification of gemstone. Specific gravity of Ekanite is 3.90-4.05 whereas that of Star Sapphire is 3.90-4.05.
