In ancient times, rubies were believed to have magical powers and were worn as a talisman for protection against evil spirits. In Sanskrit, the word for ruby is "ratnaraj " which translates to "king of precious stones." The Burmese believed that rubies held the power of life, and warriors would embed them into their skin before going into battle. Rubies were also treasured by the Indian maharajas and European royalty. Physical Properties Rubies have a hardness of 9 on the Mohs scale, which makes them one of the hardest gemstones after diamonds. They have a specific gravity of 3.97 to 4.05 and a refractive index of 1.76 to 1.78. Rubies are typically found in hexagonal crystal shapes and have a vitreous luster.
