Dumortierite and Morganite Chemical Formula
While comparing Dumortierite and Morganite 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 Morganite chemical formula.
- Chemical formula of Dumortierite- AlAl6O3BSi3O18
- Chemical formula of Morganite- Be3Al2SiO6
Dumortierite and Morganite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dumortierite and Morganite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dumortierite and Morganite Optical Properties during the identification of gemstone. Specific gravity of Dumortierite is 2.71-2.90 whereas that of Morganite is 2.71-2.90.
