Amulet

This is a small object thought to bring good luck. Lockhart claimed to have dealt with Transmogrifican Torture in Ouagadougu by giving townsfolk protective amulets. In 11992, a booming trade in protective amulets started in Hogwarts because of Slytherin's monster. Later, when Voldemort returned a sale of protective amulets from dark creatures started up in Diagon Alley.
