While comparing Richterite and Titanite 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 Richterite and Titanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Richterite and Titanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Richterite and Titanite Optical Properties during the identification of gemstone. Specific gravity of Richterite is 3.48-3.60 whereas that of Titanite is 3.48-3.60.
