This is a very striking vintage aurora borealis necklace. The choker measures 19” and has a box clasp studded with rhinestones, and has a detachable enhancer with aurora borealis drops and pave set marcasites, measuring 1” across and from 1.5” to 2.5” in length. There is some wear due to age but no missing stones. Lovely piece to add to a collection or to wear!
