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

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