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

Ekanite and Poudretteite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ekanite and Poudretteite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ekanite and Poudretteite Optical Properties during the identification of gemstone. Specific gravity of Ekanite is 2.51-2.53 whereas that of Poudretteite is 2.51-2.53.
