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 a-alumina (the most stable form of Al2O3) in which a small fraction of the aluminium3+ ions are replaced by chromium3+ ions. Each Cr3+ is surrounded octahedrally by six O2- ions.Improving the quality of gemstones by treating them is common practice. Some treatments are used in almost all cases and are therefore considered acceptable. Who should wear a Ruby? Ruby is the birthstone for Leo sun sign. In Indian astrology, Ruby stone strengthens Sun (Surya) and is the rashi ratna for Leo (Simha). Ruby gemstone (also known as 'Manikya' in Hindi) bestows wealth, status, respect, dignity and the powers of the Sun God upon its wearer. Ascendants of Aries, Cancer, Sagittarius, Pisces and Scorpio can also wear a Ruby stone.
