Anhydrite and Schorl Chemical Formula

While comparing Anhydrite and Schorl 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 Anhydrite and Schorl chemical formula.

Anhydrite and Schorl Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Schorl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Schorl Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 3.18-3.22 whereas that of Schorl is 3.18-3.22.
