Covellite and Prase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Covellite and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Covellite and Prase Optical Properties during the identification of gemstone. Specific gravity of Covellite is 2.64-2.69 whereas that of Prase is 2.64-2.69.
