Vintage Triangle Earrings

Big silver triangle earrings with cobalt and royal blue beads. Vintage, beautiful never worn, silver mental has never tarnished. I think these are from the 70’s I was told when I bought in the 90’s. Don’t want to give them up but they aren’t being used, making room in jewelry collection Cobalt blue is the new trend color for nails I also have a beaded ring bracelet that is this blue color listed.
