Datolite and Rhodolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Datolite and Rhodolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Datolite and Rhodolite Optical Properties during the identification of gemstone. Specific gravity of Datolite is 3.84 whereas that of Rhodolite is 3.84.
