Vintage Gold Plated Scarab Circle Brooch

I’ve had this brooch in my collection and stored. I’ve research this brooch, I’ve found from other platforms, sellers are stating semi precious stones. I doubt it. They have the effect of solid gold and real stones. this brooch is gold plated. For it to retain it’s beauty all these years, it’s a quality piece. There is no hallmark. It’s a lovely piece to be worn with a suit, or perhaps convert to a pendant by using an adapter. Beautiful condition.
