Would You Do This?

Watching Pawn Stars tonight. They had a guy come in with a very old, about 250 year old gun and he traded it for $2500 for store credit. He said he will use it for an engagement ring for his bride to be.
So my question is this: If you knew your hubby to be traded a gun for a engagement ring that was pawned, would you accept it or would you throw it back in his face?
