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

Labradorite and Anorthoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Anorthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Anorthoclase Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.56-2.62 whereas that of Anorthoclase is 2.56-2.62.
