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