According to some customs, the wedding ring forms the last in a series of gifts, which also may include the engagement ring, traditionally given as a betrothal present. This tradition was already in use in Ancient Rome and is possibly much older. Among Eastern Orthodox and Eastern Catholic Christians, the exchange of rings is not technically part of the wedding service, but rather are exchanged at the betrothal. It is always a two-ring set given to her by the priest or by the best man. The orthodox Christian Church of Greece has recently stopped performing betrothal blessings separately, as these were often non-committing, and a betrothal ceremony is the initial part of the wedding service anyway. In many families an informal blessing is now performed by the betrothed ones' parents in a family dinner that formalizes the betrothal. The ceremony of betrothal is now possibly performed immediately before the wedding (or "crowning" as it is more properly called), and the actual symbolic act of marriage is not the exchange of rings, but the public proclamation of marriage by an authority figure or leader. The future bridegroom may also give his future bride a jeweled ring (in North America since the 1930s, most commonly set with a diamond (see Engagement Ring) upon proposing to her. After the wedding the wedding band is worn on the ring finger, closest to the hand, and the engagement ring is worn in front of it. The rings usually match and sometimes interlock or are fused together to form one ring.
