Sapphire
This September birthstone is said to protect from envy and harm.
Sapphires, according to medieval legend, have powerful effects on the wearer. The 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 violet blue, as well as various shades of pure blue. The most prized colors would be a medium to medium dark blue or slightly violet blue.
Sapphire is a variety of the mineral corundum, and not only occurs in blue, but in all colors of the rainbow. Pink, purple, green, orange or yellow sapphires are known as fancy-coloured sapphires. But, when they are red, they are known as rubies. For the afficionado that wants something out of the ordinary, a fancy-colour sapphire creates excitement in every colour.
