Achroite and Hanksite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Achroite and Hanksite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Achroite and Hanksite Optical Properties during the identification of gemstone. Specific gravity of Achroite is 2.562 whereas that of Hanksite is 2.562.
