Vintage Gold-Tone Clip-On Dangle Earrings with Black Stones

This is a pair of vintage clip-on dangle earrings, featuring a gold-tone metal construction. Each earring consists of a screw-back clip mechanism at the top for attachment, suggesting they were designed for unpierced ears or as a fashion accessory from an era where clip-ons were more prevalent. Below the clip, an ornate dangles section is attached. This section comprises three distinct 'teardrop' or 'leaf' shaped elements, each filled with an openwork, abstract, or possibly foliate lattice-like pattern. Two of these teardrop elements hang side-by-side, with a third, smaller one suspended between and slightly below them. From these ornate upper elements, a total of three circular, faceted black stones are suspended. Each stone is set within its own gold-tone bezel setting. The stones appear to be glass or possibly onyx, given their opaque black color and faceting. The gold-tone metal exhibits a slightly aged patina, consistent with vintage costume jewelry, but there are no obvious signs of significant corrosion, chipping, or plating loss visible in the images. The overall design suggests a mid-20th century aesthetic, possibly 1950s to 1970s, characterized by the use of clip-on mechanisms and the decorative filigree-like metalwork. There are no discernible maker's marks or signatures visible from the provided images. The craftsmanship appears to be typical of mass-produced costume jewelry of the period, with a functional and decorative quality.
