Vintage! Austrian Aurora Borealis White Crystal Necklaces - set of 4

Vintage! 1950’s. Austrian Aurora Borealis Iridescent White Crystal Necklaces set of 4 (must take all 4). You can see each one of the four necklaces hanging against the brown fabric. The rest of the images I tried to capture their sparkle. 2 are long necklaces, 2 are double stands. They are Absolutely stunning! Even more sparkly in person!
