Euclase and Corundum Chemical Formula

While comparing Euclase and Corundum 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 Euclase and Corundum chemical formula.

Euclase and Corundum Specific Gravity

Another important criteria for qualitative analysis of gemstones is Euclase and Corundum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Corundum Optical Properties during the identification of gemstone. Specific gravity of Euclase is 3.90-4.05 whereas that of Corundum is 3.90-4.05.
