Dioptase and Glaucophane Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dioptase and Glaucophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Glaucophane Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 3-3.15 whereas that of Glaucophane is 3-3.15.
