Thulite and Covellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Covellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Covellite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 4.6-4.76 whereas that of Covellite is 4.6-4.76.
