Vintage brooches Juliana?

Gorgeous and sparky Juliana style faceted prong setting brooches. Unsigned, looks like Julianna, but I’m not sure. One the pinkish purple color brooch is gold tone metal. The Smokey topaz, grey, and clear colored brooch is silver tone metal. Both have slight issues, barely noticeable. The pink one has some scratches on the pearl stone area. And the silver tone brooch has one tiny chip in one of the stones. Please see the last 2 photos for close up details. I also have measurements in the photos. Perfect for any costume jewelry collector!!
