This is a really lovely vintage Art Deco era glass bead flapper necklace. It is a long strand of graduated elongated faceted amber beads with small flat clear beads in between them as spacers. It is a continuous strand with no catch.
It measures about 32 inches total (about a 16 inch drop) and it is in very good condition. There are some small fleabite chips to the facets of some of the beads as is typical of the necklaces. It appears to be on the original string, and it is secure, but at some point should probably be restrung.
