Anorthite and Pyrite Chemical Formula
While comparing Anorthite and Pyrite 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 Anorthite and Pyrite chemical formula.

Anorthite and Pyrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anorthite and Pyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthite and Pyrite Optical Properties during the identification of gemstone. Specific gravity of Anorthite is 5.00-5.20 whereas that of Pyrite is 5.00-5.20.
