Spessartine and Lazulite Specific Gravity

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