"Antique jewelry object group: rings Country of origin: unknown Style: between Edwardian and Art Deco (more info on styles) Style specifics: As for its elegant design, this jewel has the finesse of an Edwardian piece reacting gracefully against the very geometrical forms of Art Deco that was strongly influenced by Cubism. However, because both Edwardian and Art Deco styles were contemporaries of each other, we sometimes notice pieces - like this one - that carry both influences.

Conventionally, the ring is presented as a betrothal gift by a man to his prospective bride while he proposes marriage or directly after she accepts his marriage proposal. It represents a formal agreement to future marriage. In recent years such rings have normally been set with a gemstone, usually a diamond, as a solitaire, of varying sizes, cuts, styles, and cost, but in the 19th century some were set with a pearl. In the same century the custom arose in England of separate engagement ring and wedding ring, and in very recent years such rings have sometimes been made en suite as a matching pair of similar style. In recent years, antique gemstone engagement rings are rapidly gaining in popularity. In some countries, such as the United States and the United Kingdom, it is worn on the left-hand ring finger, while in other countries, such as Poland and Ukraine, it is customary for the ring to be worn on the right-hand. Similar traditions purportedly date to classical times, dating back from an early usage reportedly referring to the fourth finger of the left hand as containing the vena amoris or ""vein of love"". In the United States and Canada today it is becoming more common, but still quite rare, that a woman will also buy her partner an engagement ring (also called a pre-engagement ring, promise ring, or mangagement ring) at the time of the engagement.
