Rubies are the gem grade red colored variety of the mineral Corundum (Al2O3), an aluminum oxide, with all other color variations of gem grade Corundum being Sapphires. Their red color is the result of trace amounts of Chromium impurities dispersed throughout the stone, altering the absorption and reflection of visible light. Rubies are a beautiful rare precious gemstone, found mostly in Southern Asia and Oceania, which have been used in fine jewelry for millennia.
