Alexandrite and Citrine Chemical Formula

While comparing Alexandrite and Citrine 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 Citrine chemical formula.

  • Chemical formula of Alexandrite- BeAl 2 O 4
  • Chemical formula of Citrine- SiO2

Alexandrite and Citrine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Alexandrite and Citrine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Alexandrite and Citrine Optical Properties during the identification of gemstone. Specific gravity of Alexandrite is 2.65 whereas that of Citrine is 2.65.
