Pandora's Box #1

This logic problem (brain teaser) named Pandora’s Box.

Situation:
Once upon a time, there was a girl named Pandora, who wanted a bright groom so she made up a few logic problems for the wannabe. This is one of them.

Clues:
Based upon the inscriptions on the boxes (none or just one of them is true), choose one box where the wedding ring is hidden.

• Golden box: “The ring is in this box.”
• Silver box: “The ring is not in this box.”
• Lead box: “The ring is not in the golden box.”
