Cuprite and Sugilite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cuprite and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cuprite and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Cuprite is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
