A vintage Art Deco style rhinestone crystal choker. The original clasp was missing and I can find no marks on the necklace.  I added a new silver plated hook and eye replacement clasp. I believe it is rhodium plated and probably from the 1950s. It is a bow style with a marquis stone in the center. The rhinestones are prong set and are very sparkly and shiny. The necklace is 14.5 inches long and in very good vintage condition.
