Ruby and Euclase Chemical Formula
While comparing Ruby and Euclase 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 Euclase chemical formula.

Ruby and Euclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ruby and Euclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ruby and Euclase Optical Properties during the identification of gemstone. Specific gravity of Ruby is 3.08-3.12 whereas that of Euclase is 3.08-3.12.
