Mid-Century Modernist Rectangular Link Necklace

This item is a vintage modernist link necklace featuring a series of repetitive, open-work rectangular panels. Each link is constructed with an organic, slightly hammered or 'brutalist' texture, which suggests a mid-20th century aesthetic, likely dating from the 1960s or 1970s. The necklace is fashioned from a gold-toned metal, though visible wear and greenish verdigris at the joints indicate a base metal composition with gold plating rather than solid gold. The links are joined by small cylindrical bars, creating a flexible drape. The piece features a fold-over clasp mechanism common to costume jewelry of that era. In terms of condition, there is significant tarnish, loss of plating, and oxidation present on the reverse and within the crevices of the links, which denotes heavy previous wear or improper storage. There are no clear maker's marks visible in the image, but the design style is reminiscent of mass-market costume jewelry manufacturers such as Monet or Trifari, though the quality appears more indicative of a secondary boutique brand. The craftsmanship shows a cast production method with manual assembly of the articulating joints.
