Harry Notices Marvolo Gaunt's Ring

As Harry prepares to leave Dumbledore's office, he notices Marvolo Gaunt's ring on one of the tables. He asks Dumbledore about it, recognizing it as the same ring Marvolo Gaunt had shown Ogden in the memory. Dumbledore confirms that it is the same ring and explains that he acquired it recently, around the same time he injured his hand. However, Dumbledore does not reveal how he obtained it or how his hand was injured, promising to share the story at a later time.
