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