Evil Eye Hanging Ornament.
Though often dubbed as 'the evil eye', the ocular amulet is actually the charm meant to ward off the true evil eye: a curse transmitted through a malicious glare, usually one inspired by envy.
That envy in turn manifests itself as a curse that will undo their good fortune.
The most common cause of the evil eye is someone who is jealous. A nonna wanting to remove the malocchio takes a bowl of water and holds a spoonful of olive oil over it. She does the sign of the cross and offers a silent prayer. She then drops three to five drops of olive oil into the water with her little finger.
When a person wears or carries an evil eye with them, it guards against misfortune happening in one's life. The evil eye brings good luck and protects you from any ill-will that could otherwise have a negative effect on your well-being or your life in general.
