Thaumasite and Uvite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thaumasite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thaumasite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Thaumasite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
