Mixed-media beaded and chain linked bracelet

This item is a contemporary-style bracelet featuring a dual-design aesthetic, appears to be constructed from two distinct segments. One half consists of small, matte black spherical beads that are stylistically consistent with lava stone or matte onyx, though the exact mineral composition is unverified without physical testing. These beads are strung together and capped with gold-toned cylindrical end-pieces. The opposing half of the bracelet is a metallic chain featuring elongated oval links, finished in a polished gold tone. The piece is secured with a large lobster claw clasp, a common fastening mechanism for modern fashion jewelry. The overall condition appears to be new or very lightly used, as indicated by the owner's notes, although these claims are unverified. There are no visible maker's marks, hallmarks, or brand signatures in the image, making identification of the manufacturer or the specific metal content (such as whether it is gold-plated or base metal) speculative. The design is consistent with modern minimalist or unisex jewelry trends frequently produced in the late 20th to early 21st century.

I have examined the image provided of this contemporary mixed-media bracelet. Based on what I can see, the piece features a bifurcated design consisting of matte black spherical beads and a polished gold-toned paperclip-style chain. I cannot verify the material composition from a photograph; while the beads have a surface texture consistent with volcanic rock or matte onyx, and the metal appears as a gold-tone finish, physical inspection would be required to determine if the metal is solid gold, gold-filled, or a plated base metal. The owner identifies the condition as 'New,' though I must treat this as a working hypothesis as minor surface wear or plating degradation is often difficult to detect in digital images without magnification. The lack of visible hallmarks or maker's marks suggests this is likely a contemporary fashion or 'costume' piece rather than fine jewelry. My estimate of $45.00–$85.00 reflects the general market demand for modern, unisex accessories of this aesthetic. This value assumes the item is high-quality gold-plating on a durable substrate; if found to be solid 14k gold, the value would increase significantly based on weight. Conversely, if it is an unbranded mass-produced piece with a thin flash-plating, the value would likely sit at the lower end or below $25.00. To provide a definitive valuation, I would need to perform acid testing on the metal, verify the bead material via a gemological refractive index or visual inspection for porosity, and search for micro-stamps on the lobster claw clasp.
