Iolite and Clinohumite Chemical Formula
While comparing Iolite and Clinohumite 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 Iolite and Clinohumite chemical formula.
- Chemical formula of Iolite- Mg2Al4Si5O18
- Chemical formula of Clinohumite- (Mg,Fe2+ ) 9(SiO 4) 4(F,OH)) 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Iolite and Clinohumite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Iolite and Clinohumite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Iolite and Clinohumite Optical Properties during the identification of gemstone. Specific gravity of Iolite is 3.13-3.75 whereas that of Clinohumite is 3.13-3.75.
