Hauyne and Girasol Chemical Formula
While comparing Hauyne and Girasol 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 Hauyne and Girasol chemical formula.
- Chemical formula of Hauyne- (Na,Ca)4-8Al6Si6(O,S)24(SO4,Cl)1-2
- Chemical formula of Girasol- SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001)
Hauyne and Girasol Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hauyne and Girasol Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hauyne and Girasol Optical Properties during the identification of gemstone. Specific gravity of Hauyne is 1.98-2.50 whereas that of Girasol is 1.98-2.50.
