Small oval brooch dangle

Small oval brooch dangle. Gold tone, metal with a turquoise blue, one pearl bead, and two purple amethyst, colored, crystal or rhinestones in a filigree design, with three chains dangling from it. Very unique would look sweet, hanging from a hat, or even dangling from a bobby pin. I found this in a vintage California store and that’s about all I know about it. Very pretty.
