Realgar and Kainite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Realgar and Kainite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Realgar and Kainite Optical Properties during the identification of gemstone. Specific gravity of Realgar is 2.15 whereas that of Kainite is 2.15.
