Should we exchange rings at the wedding with real rings or fake rings?

Some are real and some are fake. I am a wedding photographer. If the rings used by newlyweds are supervised by someone and there are no complicated steps, it is better to use real rings. If not, and the groomsmen and bridesmaids or the wedding company are not powerful enough, then it is best to use fake ones. They are sold in photographic equipment stores and are very cheap. It doesn't look very fake either.

Good luck~
