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

Anorthoclase and Moonstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anorthoclase and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthoclase and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Anorthoclase is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
