This is a very rare beaded and mirrored necklace that you can wear as a choker or as a long necklace. It has a beaded mechanism in the back that you simply slide to size, and it holds in place. I have had this myself for over forty years and purchased it from a lovely little thrift store in CA when I bought it as a teenager! Sells as is. A few missing seed beads and mirrors but does not detract from it at all. Quite cool and truly has wonderful Boho-Hippie vibes! Would be gorgeous with a belly dancing outfit as well. RARE FIND
