Cameo Collection Brooch, Bracelet, and earrings

In this lot of cameos will come with three pieces Set of screw back earrings marked WRE 12k gold filled-yellow gold Next is a Red glass cameo brooch-not marked, so it’s costume piece-Unique for I don’t see many red cameos in my treasure hunting! And it has some replaced green stones for the red ones were missing Lastly, the third piece is the lovely silver tone cameo shell of lady in center and two red ruby glass squares with swirl filigree design bracelet The clasp is marked but I can not make it out even with my loupe I am unsure of the metal content. I did find that it doesn’t pull when I put my earth magnet next to it, so it may be 800 silver?? Feel free to ask any questions and reasonable offers are welcome!!
