Item from Harry Potter by J.K. Rowling
A heavy gold ring set with a cracked black stone — both a Horcrux containing a piece of Voldemort's soul and, unknowingly, the Resurrection Stone, one of the three Deathly Hallows.
Marvolo Gaunt's ring is the intersection point of the two great mythologies of the series — Horcruxes and Hallows. The Gaunt family, descendants of both Slytherin and the Peverells, possessed it for generations without understanding that their family crest was actually the Deathly Hallows symbol and that the black stone in the ring was the Resurrection Stone itself. Voldemort, equally ignorant, murdered his father and turned the ring into a Horcrux, hiding it in the ruined Gaunt shack under heavy curses. Dumbledore found it and, in a moment of devastating weakness, put it on — not to test the Horcrux but because he recognized the Resurrection Stone and desperately wanted to see his dead sister Ariana. The curse blackened his hand and gave him approximately one year to live. He destroyed the Horcrux with the Sword of Gryffindor but kept the Stone, eventually placing it inside the first Golden Snitch Harry ever caught, to be opened 'at the close' — Harry's death.
A heavy, ugly gold ring with a large cracked black stone. The Peverell coat of arms — the Deathly Hallows symbol — is etched into the stone, though the Gaunts believed it to be their family crest. The ring sits heavy on the finger and radiates dark magic. After Dumbledore destroyed the Horcrux, the stone remained cracked but functional as the Resurrection Stone.
