Anorthoclase and Anthophyllite Chemical Formula
While comparing Anorthoclase 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 Anorthoclase and Anthophyllite chemical formula.

Anorthoclase and Anthophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anorthoclase and Anthophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthoclase and Anthophyllite Optical Properties during the identification of gemstone. Specific gravity of Anorthoclase is 2.9-3.5 whereas that of Anthophyllite is 2.9-3.5.
