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

Stibiotantalite and Anorthite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Anorthite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Anorthite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 2.77 whereas that of Anorthite is 2.77.
