Right before Harry goes to confront Voldemort and sacrifice himself, he opens the Snitch Dumbledore left him in his will. Inside, he finds the Resurrection Stone. We'd think that would be pretty handy to bring with him to face Voldemort, but instead he just uses it to hang out with some of his friends and relatives who have passed on before dropping it on the ground and facing his fate.
Quote #5
VOLDEMORT: Harry Potter: the "Boy Who Lived." Come to die. Avada Kedavra!
This is it: the moment we've been dreading since Harry viewed Snape's memories in the Pensieve. Harry goes directly to Voldemort and allows him to use the Killing Curse on him without putting up a fight.
Quote #6
HARRY: Professor, what is that?
DUMBLEDORE: Something beyond either of our help. A part of Voldemort sent here to die.
After Voldemort "kills" Harry, Harry ends up hanging out with Dumbledore in a kind of limbo, where there's also a tiny, gross-looking thing dying under a bench. According to Dumbledore, it's a tiny little part of Voldemort that's dying.
