Meionite and Achroite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Meionite and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Meionite and Achroite Optical Properties during the identification of gemstone. Specific gravity of Meionite is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
