Alexandrite and Serendibite Chemical Formula
While comparing Alexandrite and Serendibite 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 Serendibite chemical formula.
- Chemical formula of Alexandrite- BeAl 2 O 4
- Chemical formula of Serendibite- Ca 2(Mg,Al) 6(Si,Al,B) 6O 20Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Alexandrite and Serendibite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Alexandrite and Serendibite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Alexandrite and Serendibite Optical Properties during the identification of gemstone. Specific gravity of Alexandrite is 3.43-3.44 whereas that of Serendibite is 3.43-3.44.
