Dec. 28, 1997: Ron Weasley destroys Salazar Slytherin's locket deep in the Forest of Dean, Gloucestershire, by stabbing it with Godric Gryffindor's sword.
When Voldemort returned to his hometown to murder his father and paternal grandparents, he took the ring and turned it into a Horcrux. Dumbledore eventually retrieved the ring and destroyed it with the sword of Godric Gryffindor.
Following a daring infiltration mission at the Ministry of Magic during Mary Cattermole's trial, Harry – along with Ron (disguised as Mary's husband, Reginald) and Hermione – retrieved the locket. It was finally destroyed by Ron Weasley, using Godric Gryffindor's sword.
Voldemort did not even realize that Harry and Dumbledore were after his Horcruxes until after 3 of them had been destroyed (Riddle's diary, Slytherin's locket, and Marvolo's ring) and a 4th captured (Hufflepuff's cup).
Its magic was last used to recall Lily, James, Sirius and Lupin as Harry prepared to face death. Voldemort himself never learned the significance of the stone.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
It is time it was returned to you. After all, he already owned one of the Deathly Hallows: The Invisibility Cloak which he possessed for over 6 years. He put on the ring because he thought the stone would give him a chance to see his dead mother and sister again (DH33,DH35).
He does not find out when he realizes Harry's scar first starts hurting him. Dumbledore and Harry do not really talk about the pain Harry experiences in his scar until the later books, but it's sort of generally accepted that Dumbledore knows about it.
James inherited the cloak from his father, Fleamont Potter, who inherited it as a descendant of Iolanthe Peverell -- a granddaughter of Ignotus Peverell. The cloak passed down through generations of the family until it reached James and then Harry.
Although, as Dumbledore says, Harry's ability to speak Parseltongue is a skill accidentally transferred by Slytherin's actual heir, Voldemort, when he tried to kill Harry as a baby. So perhaps this is one myth with a bit of truth to it.
So when Ron said three, it wasn't a mistake. He meant there were three more horcruxes to destroy before being able to destroy the fourth and final piece which was in fact Voldemort himself.
Voldemort was Salazar's heir, and as far as it is explained, he is taking up the mission in the way he believes Salazar had intended, with the Chamber and the Basilisk.
1 Voldemort's Arrogance Was His Downfall
Perhaps Voldemort's biggest mistake was thinking he was invincible. He was extremely arrogant and believed himself to be superior to everyone around him. Ever since he was a child in the orphanage, Voldemort thought he was better than everyone else.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Additionally, when Harry touches the ring, there is a flash of images as the ring reacts to him, which Dumbledore explains as an identifiable trace of lingering Dark magic.
She noticed how Harry acted more like Voldemort when the locker was on, while Ron had acted insecure and her emotional. She knew that something was off and at that point it was in her head that he was a horcrux.
Harry eventually comes to possess all three Hallows – the cloak being inherited from his father James Potter, later understood to be a descendant of one of the Peverell brothers, the Resurrection Stone in the Golden Snitch bequeathed to him by Dumbledore, and the allegiance and mastery of the Elder Wand when he defeats ...
Because it was futile and quite impossible to do so effectively. They didn't know where they had to go.
A doe. And in his final battle with Lord Voldemort, Harry explained the significance of this to his adversary, and to us: 'Snape's Patronus was a doe,' said Harry, 'the same as my mother's, because he loved her for nearly all of his life, from the time when they were children'.
Dumbledore also gives Harry the Resurrection Stone.
After Dumbledore's death, his will leaves the resurrection stone-containing snitch to Harry. "To Harry James Potter, I leave the Snitch he caught in his first Quidditch match at Hogwarts, as a reminder of the rewards of perseverance and skill," his will reads.
After spending many months looking into Voldemort's past, Albus Dumbledore was able to track down the location of the ring and retrieve it. Though he had long since abandoned his personal quest to find the Deathly Hallows, he immediately realised that this ring contained the Resurrection Stone.
Her sacrifice gave Harry the power of love, a protection spell sealed with the blood spilled by her death.
Though Harry encountered many opportunities that deemed Avada Kedavra necessary, it remains as one of the Unforgivable Curses Harry Potter never cast. For one, he viewed the spell as an immoral practice commonly used by users of the Dark Arts.
Neville's role in the prophecy in Order of the Phoenix is frequently referred to in a hypothetical scenario where Neville was the Chosen One rather than Harry. It is often suggested that Voldemort chose Harry over Neville because of Harry's half-blood status.
