Traditionally, a band was worn to complement an engagement ring's shape and style. Today's bands are so creative and detailed in their own right -- with floral motifs or bold geometrics -- that many brides prefer a band as their engagement ring. "You can design a band that will exceed the sparkle of a large single-diamond ring -- and at less cost," says Matthew Bogosian, vice president of Michael B., a jewelry firm. Styles vary widely, but a few are particularly popular: In an eternity band, the stones are set in an unbroken circle all around the ring. A pave setting features many small diamonds placed so closely together that the metal is barely visible.
