Alexandrite and Cancrinite Chemical Formula
While comparing Alexandrite 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 Alexandrite and Cancrinite chemical formula.
- Chemical formula of Alexandrite- BeAl 2 O 4
- Chemical formula of Cancrinite- Na 2Ca 2Al 6Si 6O 24(CO 3) 2Walter Schumann , Gemstones of the world (2001) More from other references
Alexandrite and Cancrinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Alexandrite and Cancrinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Alexandrite and Cancrinite Optical Properties during the identification of gemstone. Specific gravity of Alexandrite is 2.42-2.52 whereas that of Cancrinite is 2.42-2.52.
