Vintage Multi-Strand Multicolored Choker/Necklace

This is a vintage item from an estate sale. It is a multi-strand and multicolored choker or necklace. It is about 18 inches in length so most adults would wear this as a choker. The clasp is very unusual insomuch that although a cone is a common finishing technique for seed bead necklaces, I have never come across one that is a coiled cone and flexible like this one. Very, very unusual.
