Vintage Blue Cabochon Choker Necklace

This is a vintage-style collarette or choker-length necklace featuring a series of linked, silver-toned metal settings, each holding multiple cabochon-cut stones. The necklace is designed in a bib or festoon style, with the decorative elements forming a prominent display around the wearer's neck. The stones are oval or marquise-shaped, exhibiting two distinct shades of blue: a lighter, more translucent sky blue and a darker, more opaque cobalt or royal blue. These stones are likely plastic or glass, given their uniform appearance and the commercial nature suggested by the construction. Each cluster of stones is nestled within individual, branch-like or stylized floral metal settings, which are articulated, allowing the necklace to conform to the curvature of the neck. The silver-toned metal components show some slight tarnish consistent with age, but no significant damage or missing elements are apparent. The craftsmanship appears to be commercial grade, typical of costume jewelry from the mid to late 20th century. The necklace features a chain extender with a hook clasp for adjustable length, ending in a small bead, indicating a mass-produced item. There are no visible maker's marks or signatures in the provided images. The overall condition appears good for its suspected age, with all stones intact and the metal showing typical wear expected for a vintage piece. The design evokes a mid-century modern aesthetic, possibly from the 1950s to 1970s, making it a classic example of period costume jewelry.
