Heavily Faceted Vintage Round Graduated Clear Crystal Necklace 1950's Sterling?

This listing is for an unsigned necklace made from graduated faceted crystals that are ridiculously reflective. The beads are strung on a fine, delicate chain. The clasp is possibly sterling, but is not marked. Please pay close attention to where the beads are attached to the clasp. There is piece of chain hanging down from a bicone bead. This is on the opposite side of where the clasp fastens. The bicone beads are clear, and the hardware is silver tone, as is the J clasp. The necklace measures approximately 22". There is some slack in the chain, between the beads near the clasp, (see photos ). The beads range in size from 13mm to 6mm. It is truly mesmerizing. I have several other crystal necklaces and earrings listed in my closet, take a peek. I will include a velvet dust bag for storage. Buy with confidence careful packaging promised. I love to bundle.
