Anorthoclase and Alexandrite Physical Properties

Anorthoclase and Alexandrite Chemical Formula

While comparing Anorthoclase and Alexandrite 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 Alexandrite chemical formula.

• Chemical formula of Anorthoclase- (Na,K)AlSi 3O 8Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Alexandrite- BeAl ₂ O ₄

Anorthoclase and Alexandrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anorthoclase and Alexandrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthoclase and Alexandrite Optical Properties during the identification of gemstone. Specific gravity of Anorthoclase is 3.69-3.81 whereas that of Alexandrite is 3.69-3.81.
