While comparing Clinohedrite and Rubellite 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 Clinohedrite and Rubellite chemical formula.
Another important criteria for qualitative analysis of gemstones is Clinohedrite and Rubellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinohedrite and Rubellite Optical Properties during the identification of gemstone. Specific gravity of Clinohedrite is 3.01-3.06 whereas that of Rubellite is 3.01-3.06.
