Art Deco Sterling Silver and Aquamarine Hinge Bangle

This is a vintage Art Deco style hinge bangle, likely crafted from sterling silver with an antique finish. The bracelet features a slender, circular band that opens and closes via a hinge mechanism on one side, secured by a clasp on the opposite side. The most prominent feature is a rectangular decorative plaque spanning approximately one-third of the bracelet's circumference. This plaque is composed of four distinct rectangular segments, each with a raised geometric pattern, possibly a stylized 'X' or diamond motif, against a darker, possibly oxidized or patinated background, creating a two-toned effect with the lighter raised areas. The center-right segment of the plaque houses an oval-cut, bezel-set gemstone, which appears to be an aquamarine due to its light blue-green hue and clarity. The stone is horizontally oriented within its setting. The overall design suggests an Art Deco influence, characterized by its geometric patterns and linear elements, placing its estimated age in the early to mid-20th century. Visible condition shows a moderate amount of tarnish and slight surface wear consistent with age and use, particularly at the raised portions of the decorative plaque and the general silvery areas of the band. There are no obvious signs of major damage or repair, but a thorough cleaning would likely enhance its appearance. The craftsmanship appears to be of good quality, with precise geometric cuts and a secure stone setting. No visible maker's marks or hallmarks are discernible from the image.
