Opal Necklace

The Opal necklace was a cursed Dark object, which was claimed to have taken the lives of many Muggles.

The necklace was purchased at Borgin and Burkes by Draco Malfoy, under the orders of Lord Voldemort, in 1996. During the first Hogsmeade trip of the 1996-1997 Hogwarts school year, Draco Malfoy cast an Imperius Curse on Madam Rosmerta, who was then forced to cast another Imperius Curse on student Katie Bell. Bell was ordered to take a package containing the opal necklace to Albus Dumbledore.

Harry Potter, Ron Weasley, and Hermione Granger witnessed Bell arguing with her friend, Leanne, as they were heading to Hogwarts. They noted that Katie did not seem 'herself,' acting dazed and detached. During the course of the argument, the package ripped, and the necklace touched Katie's skin through a hole in her glove. Katie rose into the air, screaming, with Leanne screaming as well and attempting to pull her down. Ron and Hermione attempted to help while Harry ran off to find someone, bumping into Hagrid and leading him back to the group. After learning the nature of the event, Hagrid carried Katie to the castle, accompanied by Harry and his two friends, who handed over the necklace to Professor Severus Snape, through the Caretaker Argus Filch. Katie was taken to St Mungo's Hospital for Magical Maladies and Injuries, where she spent much of that year recovering from the effects of the curse.
