Hauyne and Brookite Chemical Formula
While comparing Hauyne and Brookite 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 Brookite chemical formula.
- Chemical formula of Hauyne- (Na,Ca)4-8Al6Si6(O,S)24(SO4,Cl)1-2

Hauyne and Brookite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hauyne and Brookite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hauyne and Brookite Optical Properties during the identification of gemstone. Specific gravity of Hauyne is 3.87-4.14 whereas that of Brookite is 3.87-4.14.
