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