Some items can be bewitched by Dark Magic for various purposes. They then become known as Dark Magic Artefacts (or simply Dark items). The following items are associated with Dark Magic:

Cursed books: Books can be bewitched to cause harm to anyone who attempts to read them. Examples include Sonnets of a Sorcerer, which causes the reader to speak in rhymes, and an unnamed book that a person can never stop reading. Tom Riddle's Diary is both a cursed book and a Horcrux.

Hand of Glory: A severed human hand with a candle placed within it. It provides light only to the holder, and commonly attributed to thieves and plunderers. It is able to penetrate Peruvian Instant Darkness Powder.

Horcrux: Thought to be the Darkest of all objects, a Horcrux is an object (or living being) that contains a fragment of a Dark wizard's divided soul. It is used to provide protection against death.

Opal necklace: This item turned up in Borgin and Burkes, was apparently purchased by Draco Malfoy, and almost killed Katie Bell. It is cursed very heavily, to the extent that merely touching it causes nearly instant death.

Blood quill: A quill that does not require ink, as it writes with the blood of the person using it. What the user writes will be carved onto the back of his or her hand, and the blood from the words sliced into the hand will be magically siphoned and used as ink on the parchment. It is used as a torture device.
