Covellite and Eudialyte Specific Gravity
Another important criteria for qualitative analysis of gemstones is Covellite and Eudialyte Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Covellite and Eudialyte Optical Properties during the identification of gemstone. Specific gravity of Covellite is 2.74-3.00 whereas that of Eudialyte is 2.74-3.00.
