Tanzanite and Charoite Chemical Formula
While comparing Tanzanite and Charoite 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 Tanzanite and Charoite chemical formula.

Tanzanite and Charoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Charoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Charoite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.54-2.78 whereas that of Charoite is 2.54-2.78.
