Gahnospinel and Anhydrite Chemical Formula
While comparing Gahnospinel and Anhydrite 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 Gahnospinel and Anhydrite chemical formula.

Gahnospinel and Anhydrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gahnospinel and Anhydrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnospinel and Anhydrite Optical Properties during the identification of gemstone. Specific gravity of Gahnospinel is 2.90-2.98 whereas that of Anhydrite is 2.90-2.98.
