Rings, magical things

Sylvia, our eldest surviving relative, who was at our family reunion. Leaving only last week gave us many reasons to want for their not to be another. After her long-lived stay I went to replace the sheets of the guest room, when finished I realized she'd left something, a ring, beautiful with an oval-shaped ivory-colored gem in the center. Seeing this on the night stand I also noticed the whole desk had become disorganized not only this but also a card lay fluttering on the window sill, The top visibly read "To Whom May Find This". Hearing the voices of my brothers and mother I grabbed the note,  ring, and fled to my room.
