AI Appraisal Estimate

This is a pair of vintage clip-on dangle earrings featuring faceted aqua-blue crystal teardrops suspended from silver-tone metal bails. Each earring consists of a mechanical clip-on fastener with a small decorative ball at the hinge, which provides a classic mid-20th-century aesthetic. The crystals are briolette-cut or teardrop-shaped with geometric facets that enhance internal light refraction, suggestive of glass or costume crystal rather than high-end gemstones. The metal hardware appears to be a rhodium-plated or high-polish silver-tone base metal, typical of mid-century costume jewelry produced between the 1950s and 1970s. The construction utilizes a jump ring connection between the clip and the bail, allowing for movement when worn. Visible condition issues include slight oxidation or tarnish on the inner surfaces of the clips and microscopic abrasions on the crystal facets consistent with age and light wear. No designer marks are immediately visible, indicating these may be high-quality mass-produced boutique pieces from that era. The blue hue of the crystal is vibrant, often nicknamed 'aquamarine' in the context of period costume jewelry.

Based on my visual examination of these vintage silver-tone clip-on earrings, I have identified them as high-quality mid-century costume jewelry, likely dating from the late 1950s to the 1970s. The faceted aqua briolette crystals exhibit a vibrant saturation and classic teardrop geometry that was popularized by makers like Coro or Trifari, though the lack of visible hallmarks suggests they were likely produced for the boutique or department store market rather than a specific designer house. The condition is excellent for its age; while there is minor oxidation typical of silver-tone base metals on the clip mechanism, the crystal facets remain sharp with minimal 'flea bites.' The market for mid-century blue crystal remains stable, driven by collectors of 'Something Blue' bridal wear and vintage aesthetics. The value is capped by the fact that they are clip-ons (which have a smaller market than pierced) and are unsigned. This valuation is based on current online auction realizations for unbranded silver-tone glass drop earrings. Limitations: This appraisal is based solely on digital images. Without an in-person inspection, I cannot verify the exact composition of the metal or use a refractometer to determine if the stones are leaded crystal or high-quality glass. A physical examination would also allow for a search for microscopic maker's marks on the hinge or bail. For definitive authentication, testing for rhodium plating or lead content in the stones would be required.
