It depends. Many engagement rings these days do both duty, they are an engagement ring, however, they have an extra band that can be attached to the engagement ring to make it a wedding ring. *shrugs* I learned all that stuff with my $800 engagement ring I purchased for someone who wore it for a year before giving it back... However, many couples prefer a straight band for their wedding ring, so it all depends.
