Apophyllite and Lazulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apophyllite and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apophyllite and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Apophyllite is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
