Vintage Red Glass Torpedo Screw-Back Earrings

This is a pair of vintage screw-back earrings, each featuring a prominent cabochon-cut, torpedo-shaped or elongated oval red glass stone. The deep red color of the glass suggests either a ruby imitation or a specific type of 'cats eye glass' as indicated by the user; however, the image does not clearly show the chatoyancy typical of true cat's eye. The stones are bezel-set within a gold-toned metal frame, which appears to be brass or a gold-plated base metal due to the visible wear and patina. The setting includes visible prongs at the top and bottom of each elongated stone, securing them firmly. The metal portions exhibit signs of age, including tarnishing and some areas where the plating may have worn off, particularly on the screw mechanisms and the backs of the settings. The screw-back closure system, common in pre-pierced earlobe eras, indicates a likely manufacturing period from the early to mid-20th century, possibly 1930s to 1950s. The craftsmanship appears to be typical of mass-produced costume jewelry of that era, with a focus on visual appeal rather than intricate detailing. No specific maker's marks or signatures are discernible from the provided images. The overall condition suggests regular use, displaying the expected wear for an item of its age, but no overt damage like cracks in the glass or significant bending of the metal beyond typical age-related deformation.

Upon examining the images provided, I have assessed this pair of vintage screw-back earrings. The design features elongated, torpedo-shaped red glass cabochons set in a gold-toned base metal, likely brass or a similar alloy, consistent with costume jewelry from the mid-20th century, approximately 1930s-1950s. The screw-back mechanism is a key indicator of this era. The owner's note of 'cats eye glass' is plausible for this period's costume pieces, though the characteristic chatoyancy is not visible in the photos. The overall condition is fair to good for its age, showing expected wear, patina, and some plating loss, but no significant damage to the glass or metal structure. The value is primarily driven by its vintage aesthetic and appeal as a collectible costume piece rather than by intrinsic material worth. The market for unsigned costume jewelry of this type is generally modest. Comparable unsigned glass earrings from this period typically sell in the lower price range. The lack of a designer or maker's mark significantly limits the value, as signed pieces (e.g., by Hattie Carnegie, Miriam Haskell, or Trifari) command much higher prices. For a definitive appraisal, an in-person examination is necessary to test the metal content, confirm the type of glass, and search for any faint or hidden maker's marks. Without physical inspection, this appraisal is based on the visible characteristics and market data for similar, unsigned vintage jewelry.
