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

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