Vintage lot of blue glass or plastic beads set in gold toned metal base. I think they are a plastic bead, but unsure. They measure slightly less than 1/4 inch in diameter. Estate jewelry sale purchase, and I don't know exactly what they're for! In good condition, a few have discoloration/darkening of the metal. About 7 are missing the metal edge and/or prongs. I'm not sure if these can be set or glued into jewelry pieces, or are for other craft purposes. I'm hoping someone knows what they are and can use them!
