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

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