It all begins with an engagement ring ..., when two partners vow marriage. This wonderful tradition is coming back again, its roots dating back to the ancient times, to the time of the cave people. The first diamond engagement rings were noted already in Ancient Greece. Most believe that the form of the ring is round, because of the form of the finger, but it is not so. The form stems from the circle, manifesting eternal love, which never ends. Today the most popular engagement rings for those in love are diamond ones, which symbolize love and eternity.
