Ruby is the reddish version of a mineral called corundum, which also includes sapphire. The red, sometimes pinkish or brownish color of ruby corundum is due to the presence of chromium. It is the fourth hardest mineral (index 9 on the Mohs scale), after diamond, lonsdaleite and moissanite. Our natural ruby is rolled in Burma, the main producer of this rare stone. Today, ruby elixirs are still attributed with revitalizing and disinfectant virtues. A stone of life, it gives courage and loyalty to its wearer. It symbolizes happiness and burning fire. It is primarily associated with the 4th chakra, that of the heart.
