Baryte and Realgar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Baryte and Realgar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Baryte and Realgar Optical Properties during the identification of gemstone. Specific gravity of Baryte is 3.56 whereas that of Realgar is 3.56.
