Having been highly desired for many centuries, sapphires have picked up a multitude of meanings from different cultures. Most lore surrounds blue sapphires which are connected to the blue sky, purity (mental and physical), and spirituality in general. Many differently colored sapphires in addition to the blue variety can be worn as amulets shielding the wearer from the impure thoughts of others. The various colors are also associated with slightly different aspects of mental awareness, intuition, and wisdom. Many wear sapphire jewelry for luck.
