AI Appraisal Estimate

This is a pair of vintage-style open hoop earrings featuring an intricate cutout filigree pattern. The earrings are constructed from a yellow-toned metal alloy, likely brass or a brass-plated base metal, exhibiting a dull, aged gold color. They are medium-sized hoops with a broad band that tapers slightly towards the ends. The decorative aspect consists of geometric and curvilinear openwork, also known as pierce-work, creating a lattice-like appearances. The earrings are designed for pierced ears with standard post backings and small butterfly clutches. Regarding condition, the items show significant signs of age and wear. Most notably, there is visible green oxidation (verdigris) concentrated around the junction of the post and the hoop body, which is common in older costume jewelry containing copper. The surface finish is uneven with some tarnish and brownish patina developmental in the recessed areas of the filigree. There are no visible maker's marks or metal purity hallmarks, suggesting these are mass-produced costume jewelry pieces rather than fine jewelry. Based on the style and the type of oxidation, they likely date from the late 20th century (1970s–1990s). The craftsmanship is characteristic of commercial fashion jewelry of that era, utilizing a stamped or cast metal technique for the decorative pattern.

I have examined the images of these vintage open-hoop filigree earrings. Based on my visual analysis, these are mid-to-late 20th-century costume jewelry pieces, likely manufactured between 1970 and 1990. The construction employs a base metal alloy, confirmed by the presence of verdigris (green copper carbonate) at the post-mount, a classic indicator of non-precious copper-based materials. The lack of hallmarks or designer signatures further classifies this as commercial, mass-produced fashion jewelry. The condition is fair to poor; the oxidation and loss of plating significantly detract from the aesthetic and structural integrity. In the current secondary market, there is a high supply of unsigned vintage brass-toned hoops, and collector demand for non-designer pieces in this condition is low. Comparables sold on platforms like Etsy or eBay frequently fetch between $8 and $22 depending on the cleanliness of the filigree. The primary value-diminishing factor is the heavy tarnish and corrosion, which requires professional remediation to be wearable. Limitations: Because this examination was conducted via photograph, I cannot definitively confirm the metal composition or the stability of the posts. A physical inspection would be required to test for nickel content (a common allergen in this era) and to verify if the green oxidation has caused structural brittleness at the solder points. No provenance was provided; however, given the mass-market nature of the casting, documentation would likely not alter the valuation significantly unless a specific celebrity association was established.
