Vintage Shell Cameo Screw-Back Earrings with Rhinestone Accents

A pair of vintage oval-shaped cameo earrings, likely dating from the mid-20th century (circa 1940s-1950s). Each earring features a hand-carved shell cameo depicting the profile of a woman with upswept classic hair, set within a gold-toned metal frame. The shell shows characteristic layered coloring with a creamy white figure against a peach or light tan background. The frame is a decorative beaded or 'millgrain' style bezel, further embellished at the base with a small cluster of colorless rhinestones arranged in a floral or spray pattern. The construction utilizes a screw-back mechanism, which was common before the widespread popularity of pierced earrings. The metal appears to be gold-plated or gold-filled base metal, showing a light age-related patina and minor tarnishing in the recessed areas of the beaded work. One earring shows slight discoloration on the shell surface, possibly from skin oils or dust. The carving detail is of moderate quality, showing clear facial features and hair texture. There are no visible maker's marks in the provided image, but the overall style is consistent with American costume jewelry of the mid-century era. The hinges and screws appear intact and functional.

I have examined the provided images and descriptions of these vintage cameo screw-back earrings. Based on my visual analysis, I have identified them as mid-20th-century costume jewelry, likely produced between 1945 and 1955. The shell carving shows moderate skill, characteristic of mass-produced Italian imports destined for the American market. The presence of screw-back findings and the particular patina suggests a gold-plated base metal rather than high-karat gold. The condition is fair to good; while the cameos remain intact, the surface discoloration and oxidation on the metalwork are consistent with age and reduce the overall 'collector quality.' Market demand for mid-century costume cameos is currently stable but modest. Similar items without designer hallmarks (such as Trifari or Coro) regularly sell within the $40 to $70 range at auction and in vintage boutiques. The use of rhinestones instead of precious stones confirms these were intended as accessible fashion accessories rather than fine jewelry. Value is primarily driven by the 'shabby chic' aesthetic appeal rather than material rarity. Please be advised that visual inspection from images has significant limitations. A physical examination is required to test the metal for gold content (using acid or XRF testing) and to confirm the shell is genuine rather than molded resin or plastic. Authentic shell will show slight graining and growth lines under 10x magnification, which cannot be definitively confirmed here. Furthermore, checking for maker's marks on the screw pads would require high-resolution macro photography or physical handling.
