Sapphires are a variety of the mineral corundum as are the equally famous and valuable Rubies. Rubies make up the red side of the family while Sapphires are all the other colors – the famous blue as well as pink, green, purple, orange and yellow. There are also black and colorless Sapphires. The traditional blue sapphire represents loyalty, wisdom, truth, sincerity and faithfulness both in religious matters and in personal relationships. Sri Lanka is the oldest known source of sapphires along with India and Burma (now called Myanmar). As of 2007, Madagascar has been leading the world in sapphire production, though Sri Lanka continues to be the only steady producer of fine quality blue sapphire. Sapphire is the birthstone of September.
