Rhodolite and Willemite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhodolite and Willemite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Willemite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 3.89-4.18 whereas that of Willemite is 3.89-4.18.
