NWOT Elegant Silver Jewelry Set

Silver set of Jewelry from SHEIN all bought separately but selling together. I had bought it for a New Year’s Eve party that had the theme changed from fancy to casual. The earrings far are cubic zirc but the choker necklace has rhinestones across it. The rings are Zinc Alloy metal, the Earrings are copper covered in a silver color, and I’m unsure about it the necklace but I assumed theyre the same metal as the earrings
