Magically animated figures of people or animals.
At the Quidditch World Cup, Ron bought a small model of Viktor Krum, the famous Bulgarian Seeker, which walked around and scowled (GF7) and even mimicked the real Viktor Krum's posture and way of walking (GF9). After Viktor Krum took Hermione to the Yule Ball, Harry found the arm of the little model lying on the floor of the boys' dormitory. Ron had apparently broken it (GF24).
Xenophilius Lovegood and his daughter Luna have delicately made models of creatures, all flapping wings or snapping jaws, hanging from their ceiling at home. Harry couldn't recognize them after four years of Care of Magical Creatures lessons, so they must have been pretty odd (DH20).

A small object which is thought to bring good luck. Lockhart claimed to have dealt with a case of Transmogrifian Torture in Ouagadougou by giving the townsfolk protective amulets (CS9). In 1992, when the students realised that a monster was attacking Muggle-borns, a booming trade in magical remedies and defences was carried on in secret, including protective amulets. Most if not all of the items for sale were fake (CS11).

Magical device used to keep Muggles out of a witch or wizard's house (JKR).
The suits of armour must always have some level of magic about them, since they were referred to as "creaking" along with the muttering portraits when Harry and Ron arrived at Hogwarts for their second year (CS5)
At Christmas time mysterious lights (everlasting candles, evidently) shine from inside every suit of armour in the castle (PA11, HBP15). During some years they are bewitched to sing Christmas carols as well (GF22).
According to Phineas Nigellus, goblin-made armour does not require cleaning, because goblins' silver repels mundane dirt, imbibing only that which strengthens it, such as basilisk venom. In this context, "armour" also includes blades such as swords (DH15).

Miniature version of stars and planets, useful for studying astronomy.
miniature model of the solar system, contained within a glass dome, each of the moons glimmered in place around the nine planets and the fiery sun, all of them hanging in thin air beneath the glass - Trelawney used one as she taught astrology in Divination (GF29)
