Eudialyte and Adamite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Eudialyte and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eudialyte and Adamite Optical Properties during the identification of gemstone. Specific gravity of Eudialyte is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
