Can a jeweler put a princess cut diamond in a round setting?

I want to have my diamond put in a different ring.|||Yes. It all depends on the size of the princess diamond in comparison to the round setting whether or not the original setting can be used. Good news...A new princess head can be easily reset in the new ring to make it work.|||Yes, he can rework the top of the setting so it will fit, depending on how fancy the band is.|||I don't think so. Princess cut is a square cut and so it not possible to set the diamond in a round setting.
