Gold Tone Chain with Opal-like Pendant

The item appears to be a tangled gold-colored chain, possibly a necklace, packaged in a plastic bag. The chain has a woven or serpentine texture, giving it a snake-like appearance. Attached to the chain is a pendant or charm, which seems to feature a single, prominent stone displaying play-of-color characteristic of an opal. The stone has a somewhat amorphous, possibly irregular, shape. The chain includes a clasp mechanism, visible as a rectangular component, suggesting it functions as a closure. Due to the lighting and packaging, the precise material (karat of gold, if real gold) and exact size of the stone and chain are not clearly discernible. There are no visible manufacturer's marks or stamps in the image. The overall condition is difficult to assess definitively while within the packaging, but the chain appears to be tangled. The item exhibits a bright, shiny, gold-like hue. The craftsmanship appears to be standard for this style of chain. The presence of the plastic bag suggests it is either new, being stored, or in transit.
