Datolite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Datolite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Datolite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Datolite is 3.1 whereas that of Thulite is 3.1.
