Vintage Mid-Century Gold-Tone Brooch with Aqua Blue Stones & Necklace Bail

Gorgeous yellow gold tone art deco mid-century brooch. Intricate flowing open scrollwork details and riveted construction with aqua colored clear faux gemstones. Estimated production era is ~1940s-50s. Pin and rollover clasp are in great working condition. This brooch has a bail and can be worn as a pendant on a necklace. Not signed. Does not have affinity with a magnet. The way the brooch assembly attached indicates this is likely gold plated. Callout: all stones are intact. One on the top right of the cluster is off-center in its setting. It does not move or I would have tried to reset it, but feared doing harm as an amateur.
