Dioptase and Povondraite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dioptase and Povondraite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Povondraite Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 3.26 whereas that of Povondraite is 3.26.
