Tiger's Eye is a protective stone. It is used as a protector against the “evil eye,” and the Blue variety of Tigers Eye shares these properties along with the more commonly found gold/brown variety. Blue Tigers Eye is a useful aid to memory and mental agility as it helps to integrate the right and left sides of the brain. It also differentiates between wishful thinking about what you think you want and what you actually need. Blue Tigers Eye has a healing effect on the nerves and clams the over-anxious or phobic.
