This is just the coolest glass necklace! I don’t think I have ever seen beads like this with so many colors. I would love to know how these were made. Graduated faceted glass beads with a marbled swirl of colors. It does give a glow in the dark with a black light. There are small clear glass spacer beads between each. Simple spring ring clasp. The necklace is 16” and in great condition. I know one of the pictures it looks like a bead is chipped, but it is not. Very unique vintage necklace.
