September Birthstone

In ancient times, sapphire was used to ward off black magic, as it renders evil powers useless.
Sapphire, the September birthstone, has been popular since the Middle Ages and, according to folklore, will protect your loved ones from envy and harm. Medieval clergy wore sapphires to symbolize heaven, while commoners thought the gem attracted heavenly blessings. Blue sapphires range from very light to very dark greenish or violetish blue, as well as various shades of pure blue. The most prized colors are a medium to medium dark blue or slightly violetish blue. Sapphire is a variety of the gem species corundum and occurs in all colors of the rainbow. Pink, purple, green, orange, or yellow corundum are known by their color (pink sapphire, green sapphire). Ruby is the red variety of corundum. 
Even though blue is the only color associated with sapphires, they come in various other colors as well. They are one of the hardest, durable minerals. Sapphires render the qualities like clear thinking and wisdom to the people born in September. Sincerity and faithfulness represent the inherent spirit of sapphire.
