AI Appraisal Estimate

A pair of vintage clip-on costume jewelry earrings featuring a stylized crescent or paisley-inspired sweep design. The earrings are constructed from a gold-toned base metal and heavily embellished with various accents. Each earring showcases a large, circular 'Aurora Borealis' (AB) coated rhinestone at the base, which exhibits a shimmering iridescent play of blue, pink, and yellow light. Following the curved sweep of the metal, there is a row of smaller faceted AB rhinestones set in a channel-like arrangement. Inset within the curve are three graduated faux cream-colored pearls of differing sizes, providing a textural contrast to the faceted stones. The craftsmanship is typical of high-quality mid-century costume jewelry, likely dating from the 1950s or 1960s when the AB coating (developed by Swarovski in 1955) was at its height of popularity. The condition appears fair to good; there is visible wear on the faux pearls where the nacreous coating has slightly dulled, and some minor metal oxidation is present. The primary stones remain bright and intact. No visible maker's marks are discernible from the frontal view, but the complexity of the stone setting suggests a reputable manufacturer from that era.

I have virtually examined this pair of mid-century costume jewelry clip-on earrings. The design is a classic 1950s-1960s sweeping crescent motif featuring Swarovski-developed Aurora Borealis (AB) rhinestones and faux pearls. My assessment of the condition is fair to good. While the AB rhinestones retain strong fire and structural integrity, the faux pearls show noticeable nacre loss and dulling, which is a common degradation in vintage plastics and glass-based coatings. The gold-tone metal displays minor oxidation consistent with age. Market demand for unsigned mid-century costume jewelry remains steady but price-sensitive. Comparables for unsigned pieces with visible wear typically sell in the $30 to $50 range, while pristine examples or those with marks such as 'Trifari' or 'Coro' fetch higher premiums. The primary factor limiting the value here is the lack of a visible maker's mark and the condition of the pearl finish. It is important to note that this appraisal is based solely on visual evidence. A physical inspection is required to determine the base metal composition, verify the security of the prong settings, and check for hallmarks on the ear clips. To fully authenticate these as a specific designer piece, one would need to cross-reference the design with period catalogs or original packaging. Given the current information, they are valued as high-quality, anonymous production pieces from the peak era of the Aurora Borealis trend.
