For auction this vintage 1950s 3-strand black irridescent bead necklace with a silver tone hook clasp. The beads are a faceted glass and have a Aurora Borealis coating on them that makes them shine other colours as well like yellow, purple, blue etc. They are graduated and have little black spacer beads between them. The necklace measures 33cm /13 inch at the shortest strand with an extension chain of 6cm. The glass necklace is in good vintage condition with only the odd bead nibble here and there. Coating is mostly intact and fastener working well. Beads shimmer nicely. Stylish necklace.
