Heavily Faceted Vintage Aurora Borealis Clear Crystal Single Strand Necklace

This listing is for an unsigned necklace made from aurora borealis crystals that are beautifully reflective. The bicone beads are clear, and the hardware is silver tone, as is the clasp. It measures approximately 18". It is truly mesmerizing. The largest beads are 10mm. It has been run through the ultra sonic cleaner, so it is free of residue. The clasp is brushed and in perfect working order. The stone on the clasp does have a little discoloration. I would date this around 1960's. I will include a velvet dust bag for storage. I have a similar dual strand necklace listed in my closet, as shown in the last photo. This listing is only for the single strand. Buy with confidence careful packaging promised. I love to bundle.
