Alexandrite and Thomsonite Chemical Formula
While comparing Alexandrite and Thomsonite 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 Thomsonite chemical formula.

Alexandrite and Thomsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Alexandrite and Thomsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Alexandrite and Thomsonite Optical Properties during the identification of gemstone. Specific gravity of Alexandrite is 2.25-2.40 whereas that of Thomsonite is 2.25-2.40.
