AI Appraisal Estimate

This is a vintage two-piece costume jewelry set consisting of a chevron-style necklace and a pair of matching drop earrings. The necklace is approximately 7 inches in length when laid flat (suggesting a total circumference of roughly 14-15 inches) and features a single row of clear round-cut rhinestones set in a silver-toned metal base. The center of the necklace forms a 'V' chevron pattern accented by light blue, square-cut or baguette rhinestones. The construction appears to be a classic articulated cup-chain design, typical of mid-20th-century costume jewelry, likely dating from the 1950s or 1960s. The earrings mirror this design with a clear-stoned diamond-shaped drop leading to a blue-stoned chevron point. They appear to be post-backed rather than screw-back, which may indicate a slightly later production date or a modification. The metal shows minor signs of oxidation and patina consistent with age. There is visible yellowing in some of the clear stones, suggesting the adhesive or the foil backing has aged. The clasp on the necklace is a fold-over style, a hallmark of mid-market vintage costume pieces. No visible maker's marks or signatures are discernible from the image, but the craftsmanship is consistent with mass-produced quality from brands like Trifari, Coro, or Lisner.

This vintage two-piece costume jewelry set displays characteristics of mid-20th-century mass-market production, likely dating to the late 1950s or early 1960s. Upon my visual examination, the set features a classic articulated cup-chain construction with clear round-cut rhinestones and blue square-cut accents. The condition is fair to good; however, I observed significant 'greying' and yellowing in several clear stones, which indicates moisture infiltration or the deterioration of the foil backing—a common issue that negatively impacts value. The metal shows minor oxidation consistent with age. The use of post-backings on the earrings, while the necklace uses a period-correct fold-over clasp, suggests a potential later modification or a late-period production date. The absence of a visible hallmark (such as Trifari or Coro) suggests this is an 'unsigned beauty,' which typically commands lower prices than branded equivalents. In the current secondary market, vintage rhinestone sets are frequently traded, making them relatively common. Demand remains steady for bridal and prom accessories, but the condition issues of the stones limit this set's collectibility. Without a physical inspection, I cannot confirm the base metal composition or test for lead/tin content. A full authentication would require a loupe examination to search for hidden signatures on the clasp or jump rings and a physical test of the stones' settings to ensure durability. Values are based on recent realized auction prices for similar unsigned blue and clear rhinestone sets in comparable condition. This appraisal is a professional opinion based on visual evidence and is not a guarantee of authenticity or resale value.
