In some cultures the wedding ring is worn on the ''ring finger'' of the left hand and in others it is on the right hand. Traditionally, a wedding ring was worn only by the bride/wife, but in recent times more men also wear a wedding ring. It is also the custom in some cultures to wear an engagement ring on the ring finger.
