Eudialyte and Malachite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Eudialyte and Malachite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eudialyte and Malachite Optical Properties during the identification of gemstone. Specific gravity of Eudialyte is 3.25-4.10 whereas that of Malachite is 3.25-4.10.
