The listing, TuVous Jasmine Necklace has ended.
Costume Jewelry. Gold metal. New, never worn but not my style. Retail Value was $10. Description on TuVous says 20 1/2" plus 3" extension. I measured about 6 1/2 inches on each side for the chain from the clasp to inlay piece plus the 3" extension and about 4" for the piece with the inlay from top to bottom. The black pieces in the inlay look like black plastic. Not sure about the shell looking pieces. They may be too.
