Lazulite and Topazolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazulite and Topazolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Topazolite Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 3.70-4.10 whereas that of Topazolite is 3.70-4.10.
