Xonotlite and Howlite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Xonotlite and Howlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Xonotlite and Howlite Optical Properties during the identification of gemstone. Specific gravity of Xonotlite is 2.45-2.58 whereas that of Howlite is 2.45-2.58.
