Silver-tone clip-on earrings with dark cabochons (unverified)

The item features a pair of clip-on costume earrings presented on a dark polishing cloth. Each earring is designed with an oval, highly reflective dark cabochon center, which appears polished and metallic or mineral-like in finish, reminiscent of hematite or dark obsidian. The central stone is surrounded by a textured, sculptural silver-tone metal bezel featuring beaded and ropetwist border details. The construction demonstrates mid-to-late 20th-century costume jewelry techniques, utilizing base metal with a silver-plated or silver-toned finish. The overall physical condition appears well-preserved, with minimal visible surface wear or tarnish on the metal components, though the high-gloss surfaces show slight reflections of the surrounding environment. There are no clearly legible maker's marks or stamps directly visible in the provided image to confirm a specific brand, designer, or period of manufacture. The style is consistent with vintage fashion jewelry popular during the latter half of the twentieth century, often characterized by bold, sculptural metalwork and contrasting dark stones. The identification of these pieces rests entirely upon their visual characteristics, shape, and decorative elements as observed from the photograph.

Based on what I can see in the provided photograph, these clip-on costume earrings feature an oval dark cabochon center surrounded by a textured, sculptural silver-tone metal bezel with beaded and ropetwist details. I cannot verify from a photo whether the metal components are silver-plated or simply base metal with a silver-toned finish, nor can I definitively identify the composition of the dark cabochons, which visually resemble hematite or dark obsidian. There are no clearly legible maker's marks or stamps visible to establish a brand, designer, or precise period of manufacture. Therefore, any attribution to a specific vintage costume jewelry maker remains a working hypothesis. My value estimate of $45–$85 assumes the attribution to mid-to-late 20th-century fashion jewelry is correct and reflects typical retail market behavior for similar unbranded vintage costume pieces in well-preserved condition. General market demand for vintage clip-on earrings of this aesthetic remains moderate among collectors of retro fashion accessories. If physical inspection reveals the piece to be a modern reproduction, replica, copy, or produced simply 'in the style of' vintage costume jewelry rather than a period piece, the value would likely decrease to the $15–$30 range. To confirm authenticity, materials, and potential authorship, an in-person examination by a qualified jewelry professional would be needed, alongside a search for microscopic hallmarks or expert appraisal.
