AI Appraisal Estimate

This pair of vintage clip-on or stud earrings features a bold, modernist design characterized by a circular domed form. Each earring is crafted from a matte-finished yellow metal, likely brass or a gold-toned alloy, approximately 20-25mm in diameter. The central focal point is a square-cut, deep red cabochon, possibly glass or a synthetic resin, bezel-set into a diamond orientation within the metal's center. The stones exhibit a rich, translucent ruby hue with a high-domed polish. The metal surface shows a distinct aged patina with visible micro-scratches and minor surface oxidation commensurate with mid-to-late 20th-century costume jewelry. The construction appears sturdy, with the stones flush-mounted to the metal frame, reflecting quality mass-production craftsmanship typical of the 1970s or 1980s. No visible maker’s marks are discernible from the primary view, but the geometric aesthetic is consistent with the 'Power Dressing' era of fashion jewelry. The overall condition is vintage-good, showing slight darkening of the metal finish but no significant chips to the red insets.

I have examined the digital representation of this pair of vintage circular brass earrings featuring red cabochon insets. These pieces epitomize the bold, geometric aesthetic of 1980s costume jewelry. Based on my visual assessment, the condition is 'vintage-good.' The matte brass finish exhibits a natural aged patina and minor surface oxidation, which is characteristic of high-quality base metal alloys from the late 20th century. The square-cut ruby-toned insets appear to be well-set glass or resin, showing no visible fracturing or significant abrasions. This design is highly representative of the 'Power Dressing' era, placing it in a stable market niche for collectors of retro accessories. Similar unsigned modernist pieces from this period typically realize between $40 and $80 in vintage boutiques and online marketplaces. The value is driven by the wearable design and the enduring popularity of the red-and-gold color palette, though the lack of a designer hallmark (such as Monet or Trifari) caps the collectible ceiling. It is important to note that this appraisal is based solely on digital images. A physical examination is required to confirm the base metal composition and to check the reverse for hidden maker's marks or identifying signatures. I would also need to test the stones with a refractometer or thermal conductivity probe to definitively distinguish between glass and higher-value synthetic spinels. Finally, inspecting the mechanical integrity of the clips or posts would be necessary for a full authentication of functional condition.
