Anorthoclase and Anhydrite Chemical Formula

While comparing Anorthoclase 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 Anorthoclase and Anhydrite chemical formula.

Anorthoclase and Anhydrite Specific Gravity

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