Mid-century style blue rhinestone clip-on earrings

This pair of earrings appears to be stylistically consistent with mid-20th-century costume jewelry, specifically the 1950s or 1960s. Each earring features a clustered arrangement of marquise-cut (navette) rhinestones in a light blue or periwinkle shade, accented by smaller round light-blue and possibly aurora borealis-effect stones at the top. The stones are set in what appears to be a gold-tone metal base with visible prong settings. The construction is typical of vintage costume jewelry, where glass or acrylic stones are secured within metal findings. From the provided angle, they look to be clip-on style, though the findings themselves are obscured by the front-facing view. Each earring measures approximately one inch in length. Visible condition indicates some age-related wear, including minor dust accumulation around the prongs and potential slight dulling to some of the smaller accent stones. No maker's marks, signatures, or metal purity stamps are legible in the provided photograph; therefore, any attribution to a specific designer like Weiss, Trifari, or Coro remains a hypothesis subject to in-person inspection and finding verification. The identification of a mid-century style is based on the popular navette cluster design and the specific shade of faceted blue stones common to that era.

I have examined the digital image of the mid-century style blue rhinestone clip-on earrings. Based on what I can see, the pair features navette-cut and round faceted stones in a periwinkle blue shade, set in a gold-tone metal base. While the layout is characteristic of 1950s jewelry, I cannot verify the material or maker from a photo alone; physical inspection would be required to determine if the stones are glass or acrylic and to check for hidden designer signatures. My estimate of $25.00–$65.00 is based on the assumption that these are mid-market vintage costume pieces, such as those by brands like Coro or Weiss. If a physical examination were to reveal a sought-after maker's mark like 'Trifari' or 'Schreiner,' the value could potentially exceed this range. Conversely, if they are modern reproductions or lack a designer mark, they would typically sell at the lower end of the spectrum ($10-$20). The market for vintage costume jewelry remains steady, with specific interest in periwinkle or 'aurora borealis' finishes. To confirm this appraisal, an in-person inspection is needed to examine the tension of the clips, the integrity of the foil backing on the stones, and the presence of any hallmarks. This valuation assumes the stones are intact and the metal shows only the minor wear visible in the image.
