Anthophyllite and Sodalite Chemical Formula
While comparing Anthophyllite and Sodalite 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 Anthophyllite and Sodalite chemical formula.
- Chemical formula of Anthophyllite- (Mg,Fe2+ ) 2(Mg,Fe2+ ) 5Si 8O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)

Anthophyllite and Sodalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anthophyllite and Sodalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Sodalite Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is 2.15-2.40 whereas that of Sodalite is 2.15-2.40.
