Lazurite and Vesuvianite Idocrase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazurite and Vesuvianite Idocrase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Vesuvianite Idocrase Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 3.25-3.50 whereas that of Vesuvianite Idocrase is 3.25-3.50.
