Cluster-style iridescent glass beaded earrings

This pair of earrings features a cluster-style arrangement of faceted glass beads. The central bead in each earring is a larger clear faceted glass sphere, surrounded by an outer ring of smaller bicone-shaped glass beads. Some of these beads exhibit an 'Aurora Borealis' (AB) or iridescent coating, which creates a rainbow-like shimmer when light reflects off the facets. Between the larger beads are small, spherical spacer beads in a metallic or dark glass finish. The composition appears to be wired or glued onto a metal base, though the specific backing mechanism (such as a clip-on or post) is not clearly visible from this angle. The craftsmanship is consistent with mid-20th-century costume jewelry, particularly styles popular in the 1950s and 1960s. There are visible signs of age, including apparent oxidation or surface debris on the internal metal wires or base, and some dullness to the bead surfaces. No maker's marks or signatures are visible in the image, so this identification is based purely on stylistic characteristics common to mass-market costume jewelry production from that era.

Based on the provided imagery, I have examined this pair of cluster-style earrings. The items appear to be mid-20th-century costume jewelry, characterized by faceted glass spheres and bicone beads with an iridescent coating consistent with the Aurora Borealis finish popularized in the 1950s. From what I can see, the construction utilizes wiring onto a metal base, a common technique for mass-market vintage accessories. I cannot verify the exact metal composition or the specific attachment mechanism (clip vs. post) from this angle, nor can I confirm the presence of any hidden maker’s marks. The value estimate of $15.00 to $35.00 is based on the assumption that these are unsigned vintage pieces in fair to good condition. The observed oxidation on the internal wiring and surface dullness on the beads suggest a level of wear that slightly suppresses the value compared to mint-condition examples. In the current secondary market, there is a steady but modest demand for 'mid-century' or 'atomic era' costume jewelry. If these earrings were found to bear a stamp consistent with a sought-after designer like Miriam Haskell or Schiaparelli, the value could increase significantly. Conversely, if they are modern reproductions using plastic components instead of glass, the value would likely drop below $10.00. To provide a more precise valuation, a physical inspection is required to check for hallmarks, verify the material of the beads (glass vs. acrylic), and assess the structural integrity of the wiring. Authentic provenance or original packaging would also be necessary to move beyond this hypothetical attribution.
