A crisp statement of early 20th-century machine-age design, this striking Art Deco pendant necklace is crafted in solid 800 silver with a rich, natural antique patina. The architectural centerpiece features a custom-cut, rectangular faceted synthetic blue spinel (or aquamarine paste), delivering a vibrant, icy blue hue. The focal stone is held securely within a robust, geometric openwork frame characterized by precise, blocky strut detailing typical of the era. Suspended from a sleek, polished bail on a sturdy silver box chain, the pendant rests beautifully on the chest and is stamped with an authentic 800 silver purity hallmark on the reverse.
