Lazurite and Hyalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazurite and Hyalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Hyalite Optical Properties during the identification of gemstone. Specific gravity of Lazurite is Not Available whereas that of Hyalite is Not Available.
