Sugilite and Linarite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sugilite and Linarite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Linarite Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 5.35 whereas that of Linarite is 5.35.
