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

Anhydrite and Pollucite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anhydrite and Pollucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Pollucite Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 2.86-2.94 whereas that of Pollucite is 2.86-2.94.
