Lazurite and Hanksite Chemical Formula
While comparing Lazurite and Hanksite 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 Lazurite and Hanksite chemical formula.
- Chemical formula of Lazurite- (Na,Ca) 8Al 6Si 6O 24(SO 4,S,Cl) 2Ulrich Henn and Claudio C.
- Chemical formula of Hanksite- KNa22(SO4)9(CO3)2Cl
Lazurite and Hanksite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazurite and Hanksite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Hanksite Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 2.562 whereas that of Hanksite is 2.562.
