Vintage Aquamarine Glass Rhinestone Wreath Brooch

This is a circular wreath-style costume jewelry brooch, likely dating from the mid-20th century (circa 1950s-1960s). The piece is constructed with a silver-tone metal base, featuring a classic prong-set arrangement. It prominently displays eleven marquise-cut (eye-shaped) faceted glass rhinestones in a vibrant aquamarine or sky blue hue. These larger stones are arranged in an overlapping, clockwise radial pattern that creates a sense of movement. Interspersed between and bordering the larger stones are clusters of smaller, round-cut clear or light blue chaton rhinestones, also secured in individual metal prongs. The overall diameter appears to be approximately 1.5 to 2 inches. In terms of condition, there is visible darkening and oxidation on the metal prongs, common for vintage pot metal or rhodium-plated alloys. The stones appear to be intact without major chips, though some of the smaller round stones show signs of 'greying' or foil backing degradation, which is typical for stones of this age. The craftsmanship reflects mass-produced but high-quality mid-century costume jewelry, characterized by sturdy prong settings rather than simple adhesive. No designer mark is visible from the front view, though its aesthetic is consistent with manufacturers like Coro or Trifari of that era.
