Afghanite and Xonotlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Xonotlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Xonotlite Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 2.71-2.72 whereas that of Xonotlite is 2.71-2.72.
