Eudialyte and Anorthite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Eudialyte and Anorthite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eudialyte and Anorthite Optical Properties during the identification of gemstone. Specific gravity of Eudialyte is 2.77 whereas that of Anorthite is 2.77.
