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