Sapphire and Seraphinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sapphire and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
