Vintage Filigree Clip-On Earrings with Blue Rhinestones

This is a pair of vintage clip-on earrings featuring a floral or snowflake-like design. Each earring is crafted from what appears to be a brass or gold-toned metal, which exhibits some darkening and patina consistent with age, suggesting it might be an unplated base metal or plated brass where the plating has worn down. The construction is elaborate, with a central large, round facet-cut artificial gem in a vibrant turquoise or aqua blue hue. Surrounding this central stone are six smaller, individual flower-shaped settings, each adorned with a tiny, round facet-cut artificial gem of the same blue color. The metalwork around these smaller stones includes delicate filigree or openwork, forming petal-like shapes, which contributes to the overall intricate design. The back of one earring clearly shows a functional clip-on mechanism, indicating these are designed for unpierced ears. There are no visible maker's marks or signatures in the image. The condition shows moderate wear, with some visible scratches on the metal and the stones, and the aforementioned darkening of the metal. The stones appear to be foil-backed or set in closed-back bezels, which is common for costume jewelry from the mid-20th century. The overall aesthetic points to a mid-century (circa 1940s-1960s) costume jewelry style, characterized by bold colors and intricate, often floral or geometric, patterns.
