Vintage blue aurora borealis crystal bead necklace with gold-tone spacers

This necklace features blue aurora borealis crystal beads, which were extremely popular in the 1950s after Swarovski developed the aurora borealis coating technique in collaboration with Christian Dior in 1955. The graduated design with larger beads at the center and smaller ones toward the clasp was a classic mid-century jewelry styling technique. Aurora borealis crystal jewelry became a staple of mid-century fashion, prized for its iridescent qualities that shimmer with multiple colors when light hits the surface. These pieces are highly valued by vintage costume jewelry collectors and mid-century modern enthusiasts who appreciate the craftsmanship and distinctive aesthetic of the post-war era.
