Okay, if you're referring to the boy standing in front of the large circular crystal, which I believe you are, then just talk to him and expose the Cloudy Mirror to the crystal. It'll change into the Celestial Mirror afterwards.

I really don't understand how you'd have a problem with that, unless it were a glitch of some sort.
