Cut and Carat (mass)|carat (size) also determine the price.

Physical properties
Rubies have a hardness of 9.0 on the Mohs scale of mineral hardness. Among the natural gems only moissanite and diamond are harder, with diamond having a Mohs hardness of 10.0 and moissonite falling somewhere in between corundum (ruby) and diamond in hardness. Ruby is Î±-alumina (-the most stable form of Al2O3) in which a small fraction of the Aluminum3+ ions are replaced by Chromium3+ ions. Each Cr3+ is surrounded octahedrally by six O&
