Vintage Gold-Tone Serpent Chain Keychain with Large Faceted Rhinestone

This item is a vintage decorative keychain or fob featuring a striking combination of a large clear gemstone and classic jewelry-inspired metalwork. The item is constructed from gold-toned metal, likely brass or a gold-plated base metal. It features a large, oval-faceted clear stone at the top, which appears to be glass or a high-quality cubic zirconia, held in place by a decorative scalloped or crown-style prong setting. Attached to this setting is a short, flexible 'serpent' or 'snake' style chain that provides fluid movement. This chain connects to a basic split-ring key holder. The overall craftsmanship suggests a mid-to-late 20th-century fashion accessory, possibly from the 1960s or 70s given the style of the chain and oversized rhinestone. In terms of condition, there is visible tarnish and wear to the gold finish on the split ring and parts of the snake chain, revealing a silver-colored base metal underneath. The stone shows some surface dust and minor cloudiness typical of aged glass but appears free of major chips. There are no visible maker's marks or signatures, suggesting it may be a mass-produced boutique item or costume jewelry accessory from that era.
