Aurora Borealis 1950's Faceted Crystal Bead Necklace

All the rainbow colours are reflected in the light provided by the aurora borealis coating on these beads, which was developed by Swarovski in the early 1950's. These are particularly colourful reflecting greens, purples, pinks, blues. Each bead is separated with a tiny clear crystal bugle bead.   They graduate in size from the central large bead with a measurement end to end of 43cms finished with a marcasite set push in clasp. In very good condition, gift boxed by Vintageonline.
