Oval cabochon-style stud earrings with rhinestone halo

This pair consists of two oval-shaped post-back stud earrings, which are stylistically consistent with late 20th-century costume jewelry. Each earring features a central white, opaque oval cabochon, likely made of resin, glass, or a similar plastic material, designed to simulate the appearance of opal or milk glass. The central stones are surrounded by a halo of small, clear, round-cut stones that appear consistent with glass rhinestones or cubic zirconia. These secondary stones are set into a gold-toned metal frame with a textured or beaded edge. The metal finish shows visible signs of age and wear, including darkening and slight tarnish in the crevices between stones, which is common in plated base metals. There are no visible maker's marks, hallmarks, or signatures legible in the image; therefore, any specific brand attribution would require a physical inspection of the reverses or posts. The owner describes these as earrings, which is supported by the visible earring posts and butterfly clutches. The craftsmanship appears to be typical of mass-produced fashion jewelry rather than fine jewelry, given the setting style and visible wear on the metallic finish.

Based on my visual analysis of the provided images, these earrings appear to be costume jewelry consistent with late 20th-century fashion production. I am basing this appraisal on the 'in the style of' assumption that the materials are non-precious, including synthetic cabochons and glass rhinestones set in a plated base metal. From the photo, I can see significant wear and darkening of the gold-toned finish, which typically indicates a lack of high-karat gold content. I cannot verify the specific metal composition or the identity of the stones without a physical inspection or acid testing. The absence of visible hallmarks or maker's marks, as noted by the user, suggests these were likely mass-produced for the general retail market. The value estimate of $15 - $40 reflects current market trends for unbranded, vintage costume jewelry in fair to good condition. If these were found to be by a specific high-end designer like Dior or Trifari upon closer inspection of the posts or clutches, the value could potentially reach $75 - $125. Conversely, if the metallic finish continues to degrade or the stones show signs of adhesive failure, the value would fall toward the lower end of the spectrum. To confirm this appraisal, an in-person examination would be required to rule out the presence of precious metals and to better assess the stones under magnification. At present, the market demand for generic mid-to-late century costume earrings remains stable but modest.
