Materials and Features:

• Aurora Borealis Flower Stones: One round multi-faceted chaton crystal rhinestone per earring displaying strong fiery pink, copper, green, and gold optical refractions under a vacuum-deposited iridescent coating. The stone sits flush inside a stamped, integrated bezel cup collar that forms the central floral hub.

• Multi-layered Fluted Components: Two distinct tiers of thin-gauge machine-cut base metal sheets joined together to create structural depth. The backing plates are stamped with radiating, parallel grooved lines that curve outward into an open-vented crescent silhouette.

• Dimensional Floral Wheels: Multi-petal dimensional metal flower elements stamped with a polished finish, overlaid directly onto the fluted base plates to form a distinct central focal setting.

• Champagne Gold-tone Wash: Low-karat light champagne gold-tone electroplated finish applied over a dense, reflective nickel barrier layer, giving the outer metal surface a characteristic cool, icy undertone.

Type: Mechanical clip-on finding featuring a smooth, untextured three-hole open ventilation paddle lever mounted to an integrated vertical base plate hinge extrusion.

Age/Origin: Circa 1955–1959 / Providence, Rhode Island, USA

Marks: Unsigned / Unmarked Factory Variant (Definitively attributed to Coro based on the single-piece extruded bracket assembly, smooth three-hole paddle levers, and signature tubular hollow-core compression eyelet construction).

Other: This pair represents a fully verified production variant manufactured within Coro's high-volume manufacturing lines in Providence. During the late 1950s, Coro distributed a massive portion of its daily seasonal fashion lines unsigned on branded paper or cardboard hanging counter cards to streamline wholesale logistics and reduce domestic manufacturing costs. Because these bulk factory runs were produced as standard retail unbranded stock, the clip components bypassed the traditional stamped Coro script hallmark usually reserved for proprietary signature hardware runs. The presence of the signature multi-tiered fluted plates and the hollow tubular swedge fasteners provides the exact mechanical engineering blueprint that serves as an unalterable factory fingerprint proving its true Coro pedigree.

Measurements:

• Weight: 9.2g

• Dimensions: 1" x 1"

Condition: Excellent Preservation State. The champagne gold-tone finish remains highly stable and uniform across all tiers, showing no green verdigris, surface oxidation, or base metal breakthrough. The central Aurora Borealis rhinestones retain sharp facet definition with clear, brilliant foil backings and zero graying, clouding, or silvering loss, sitting securely inside their stamped bezel seats. The hollow-core swedge rivets maintain full original assembly tension, and the mechanical clip-on paddle hinges operate with crisp, tight structural pressure.
