Omphacite and Anhydrite Chemical Formula

While comparing Omphacite 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 Omphacite and Anhydrite chemical formula.

Omphacite and Anhydrite Specific Gravity

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