Sodalite and Gedrite Chemical Formula
While comparing Sodalite and Gedrite 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 Sodalite and Gedrite chemical formula.
- Chemical formula of Sodalite- Na8Al6Si6O24Cl2
- Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Sodalite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
