While comparing Maw Sit Sit and Achroite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Maw Sit Sit and Achroite chemical formula.
Another important criteria for qualitative analysis of gemstones is Maw Sit Sit and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Maw Sit Sit and Achroite Optical Properties during the identification of gemstone. Specific gravity of Maw Sit Sit is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
