Sugilite and Cymophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sugilite and Cymophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sugilite and Cymophane Optical Properties during the identification of gemstone. Specific gravity of Sugilite is 3.69-3.81 whereas that of Cymophane is 3.69-3.81.
