Sapphire and Cancrinite Chemical Formula
While comparing Sapphire and Cancrinite 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 Cancrinite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Cancrinite- Na 2Ca 2Al 6Si 6O 24(CO 3) 2Walter Schumann , Gemstones of the world (2001) More from other references
Sapphire and Cancrinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Cancrinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Cancrinite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.42-2.52 whereas that of Cancrinite is 2.42-2.52.
