Dumortierite and Seraphinite Chemical Formula
While comparing Dumortierite and Seraphinite 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 Dumortierite and Seraphinite chemical formula.
- Chemical formula of Dumortierite- AlAl6O3BSi3O18
- Chemical formula of Seraphinite- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)
Dumortierite and Seraphinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dumortierite and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dumortierite and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Dumortierite is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
