Rhinestone collar clips with dangling pendant

This piece of costume jewelry appears to be a double-strand rhinestone collar clip or sweater guard, featuring two anchor ends connected by draped chains of small chaton-cut clear rhinestones. The item is constructed from a silver-toned metal base, likely base metal or white pot metal, set with sparkling faceted glass rhinestones. The upper anchor points feature rectangular or baguette-cut stones and utilize standard clutch-back or tack-pin fasteners, typical of accessories designed to attach securely to the lapels or collars of a garment. The central focal point consists of an arrangement of larger square and diamond-shaped prong-set rhinestones forming a geometric cluster, from which a single faceted teardrop or pear-cut rhinestone dangles freely. The metal shows minor surface wear and patina consistent with age, but the stones appear bright with strong light refraction. There are no visible maker's marks, signatures, or stamps discernible in the photograph. The style is characteristic of mid-20th-century costume jewelry, frequently associated with the 1950s or 1960s cocktail and evening wear accessories. The overall construction displays standard mid-century costume manufacturing techniques, with prong-set stones and soldered chain links. The identification is based entirely on the visual configuration of the item as a dual-pin collar accessory and remains unauthenticated.

Based on what I can see in the photograph, this piece of costume jewelry appears to be a mid-20th-century double-strand rhinestone collar clip or sweater guard featuring a dangling pear-cut pendant, likely dating from the 1950s or 1960s. The construction utilizes a silver-toned metal base set with faceted clear rhinestones using standard prong-setting techniques. However, I can't verify from a photo alone the exact metal composition, the presence of any hidden maker's marks on the reverse, or the overall structural stability. Would need physical inspection to confirm whether the stones are glass or synthetic crystal and if any repairs have been made. My value estimate of $75 to $150 assumes the attribution to mid-century costume jewelry is correct and that the piece remains in good vintage condition with bright stones and functional clasps. General market demand for vintage costume jewelry and sweater guards of this type remains steady among collectors of mid-century accessories, though prices can fluctuate based on current aesthetic trends. If physical inspection reveals that the item is a modern reproduction, an unbranded copy, or made 'in the style of' rather than a vintage period piece, the estimated value would drop significantly, likely falling into the $25 to $50 range. To confirm authenticity and better understand the item, one would need an in-person examination, a close-up check for hallmarks or signatures, and a professional appraisal by a specialist in vintage costume jewelry.
