Horcrux of Desire

Could he look into the Mirror of Erised and not lose his mind?
He looked to the ground and as he stroked the ring on his finger, he came to a decision.
He lifted his head and his lungs and heart both stopped working.
As tears formed in his eyes....he reached out a hand, his ring glinted in the dull light of the room, and touched the mirror.
Pain unbearable, and then darkness untouched.
