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