Sapphire stimulates the 3rd eye and puts you in touch with your psychic vision. It enhances the ability to "see" into the future. According to Scott Cunningham "The Greeks identified the sapphire with Apollo and the stone was worn when consulting oracles such as the one at Delphi."
It is another stone that brings peace to your surroundings, it can help dispel anger and promote understanding. It is also protective when there is anger or negativity directed at you from an outside source.
Sapphires are good for the eyes, enhancing physical as well as psychic vision.
