Dumortierite and Moonstone Chemical Formula
While comparing Dumortierite and Moonstone 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 Moonstone chemical formula.
- Chemical formula of Dumortierite- AlAl6O3BSi3O18
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8
Dumortierite and Moonstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dumortierite and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dumortierite and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Dumortierite is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
