Sapphire and Sanidine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Sanidine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Sanidine Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.54-2.61 whereas that of Sanidine is 2.54-2.61.
