Glass Crystal 3 Strand Necklace with aurora borealis finsh, Vintage Costume

Aurora borealis crystal jewelry became popular in the 1950s and 1960s, named after the northern lights due to its iridescent rainbow finish. This coating technique was developed by Swarovski in collaboration with Christian Dior in 1955, creating a distinctive shimmer effect that became iconic in mid-century costume jewelry. Multi-strand crystal necklaces were fashionable accessories during this era, worn for both daytime and evening occasions. These pieces appeal to vintage jewelry collectors and those seeking affordable glamorous accessories with retro charm.
