Uvite and Girasol Specific Gravity
Another important criteria for qualitative analysis of gemstones is Uvite and Girasol Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Girasol Optical Properties during the identification of gemstone. Specific gravity of Uvite is 1.98-2.50 whereas that of Girasol is 1.98-2.50.
