Zoisite and Hackmanite Chemical Formula
While comparing Zoisite and Hackmanite 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 Zoisite and Hackmanite chemical formula.
- Chemical formula of Zoisite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Hackmanite- Na 8Al 6Si 6O 24Cl 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Zoisite and Hackmanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zoisite and Hackmanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zoisite and Hackmanite Optical Properties during the identification of gemstone. Specific gravity of Zoisite is 2.27-2.33 whereas that of Hackmanite is 2.27-2.33.
