Marvolo Gaunt's ring

When his uncle stole Morfin (blame the guy for the death of the family), and used the grandfather Marvolo's ring to create a Horcrux, Voldemort did not know that the Resurrection Stone (one of the relics of death, the following text) was the jewel encrusted in the ring. Dumbledore found the ring and destroyed with the sword ofGryffindor, but she was impregnated by the poison of the Basilisk (Harry used it tokill the monster in 1993). Poisoned, Dumbledore sees his hand to black and Snape tells him he has a few months of life. Dumbledore hides the Resurrection Stone in Golden Snitch that Harry caught (with the mouth) in his first Quidditch match and writes his will.
