Hypersthene and Achroite Chemical Formula
While comparing Hypersthene 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 Hypersthene and Achroite chemical formula.

- Chemical formula of Achroite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) Formula given for elbaite.
Hypersthene and Achroite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hypersthene and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hypersthene and Achroite Optical Properties during the identification of gemstone. Specific gravity of Hypersthene is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
