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