Labradorite and Anthophyllite Chemical Formula
While comparing Labradorite and Anthophyllite 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 Labradorite and Anthophyllite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Anthophyllite- (Mg,Fe2+ ) 2(Mg,Fe2+ ) 5Si 8O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Labradorite and Anthophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Anthophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Anthophyllite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.9-3.5 whereas that of Anthophyllite is 2.9-3.5.
