Sugilite and Wernerite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sugilite and Wernerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Wernerite Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 2.50-2.80 whereas that of Wernerite is 2.50-2.80.
