"There is a cup," he said quietly. "Heavily enchanted. It is very important to me. I will give it to you, and trust that you will keep it as safe as I would, to put it where none save you can find it, or touch it."
Or destroy it, he added silently, but that was almost a laugh. What could destroy his cup, his horcrux?
"I know it may not sound like much," he continued gently. "What is a cup, after all, but something to drink from or something pretty for a mantle piece? But this cup has significance to me."
