While comparing Ruby and Clinohumite 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 Ruby and Clinohumite chemical formula.
Another important criteria for qualitative analysis of gemstones is Ruby and Clinohumite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ruby and Clinohumite Optical Properties during the identification of gemstone. Specific gravity of Ruby is 3.13-3.75 whereas that of Clinohumite is 3.13-3.75.
