💥Vintage Carved Cameo Blue Brooch Stone Rim💥

This is a vintage, unbranded Cameo brooch. Framed by antique silver tone filigree, with 6 pink (?) rhinestones. The cameo appears porcelain, with a cloudy blue background. I find no maker markings. Measurements as shown. Questions and offers welcome. We are a smoke free home. Thank you for your time.
