Here are the six Horcruxes:
* Tom Riddle's Diary: Hidden in the Chamber of Secrets at Hogwarts.
* Marvolo Gaunt's Ring: Worn by Voldemort as a ring.
* Salazar Slytherin's Locket: Hidden in a cave in Albania.
* Helga Hufflepuff's Cup: Hidden in Bellatrix Lestrange's vault at Gringotts.
* Rowena Ravenclaw's Diadem: Hidden in the Room of Requirement at Hogwarts.
* Harry Potter: Voldemort unknowingly created a Horcrux within Harry when he attempted to kill him as a baby.
The seventh object mentioned is Nagini, Voldemort's snake. While she was a part of Voldemort and could be considered a vessel for a piece of his soul, she was not a Horcrux. It's important to note that Nagini was a creature and could not be considered a Horcrux in the same way as the other objects.
