Sulfur and Lazurite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sulfur and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sulfur and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Sulfur is 2.75 whereas that of Lazurite is 2.75.
