Euclase and Dioptase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Euclase and Dioptase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Dioptase Optical Properties during the identification of gemstone. Specific gravity of Euclase is 3.25-3.35 whereas that of Dioptase is 3.25-3.35.
