On the pavement by your house, perfectly lit by the streetlamp above, there's a necklace.

It doesn't belong to you or anyone you know (as far as you're aware), so you leave it where it is. If it's still there tomorrow, you'll take it.

The next day, there's a necklace-shaped hole in the concrete where it used to sit.
