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

Tanzanite and Ekanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Ekanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Ekanite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 3.28-3.32 whereas that of Ekanite is 3.28-3.32.
