Sapphire
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 sapphire 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, yellow corundum are known by their color (pink sapphire, green
sapphire). Ruby is the red variety of
corundum.
