Sapphire and Wernerite Chemical Formula
While comparing Sapphire and Wernerite 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 Wernerite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Wernerite- Na 4(Al,Si) 12O 24Cl to Ca 4(Si,Al) 12O 24(CO 3,SO 4)Arthur Thomas , Gemstones (2009)
Sapphire and Wernerite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Wernerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Wernerite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.50-2.80 whereas that of Wernerite is 2.50-2.80.
