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