Prase and Anhydrite Physical Properties

Prase and Anhydrite Chemical Formula

While comparing Prase 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 Prase and Anhydrite chemical formula.

Prase and Anhydrite Specific Gravity

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