Exquisite RARE Firefly brand Vintage Swarovski Crystal Glass Beaded Necklace

Excellent condition the beads on one tiny part of necklace isn’t as tight as the others. I found this at Bergdorf Goodman but they are out of stock and I can’t find the name on this necklace my mom has had in storage for so many years. Rare and one of a kind! Fabulous piece!
