Sanidine and Lazurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sanidine and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sanidine and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Sanidine is 2.75 whereas that of Lazurite is 2.75.
