Eudialyte and Oligoclase Specific Gravity

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