Sapphire and Anorthoclase Chemical Formula
While comparing Sapphire and Anorthoclase 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 Sapphire and Anorthoclase chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Anorthoclase- (Na,K)AlSi 3O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Sapphire and Anorthoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Anorthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Anorthoclase Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.56-2.62 whereas that of Anorthoclase is 2.56-2.62.
