Anhydrite and Jet Chemical Formula

While comparing Anhydrite and Jet 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 Jet chemical formula.

Anhydrite and Jet Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Jet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Jet Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 1.19-1.35 whereas that of Jet is 1.19-1.35.
