Vtg 1950's Aurora Borealis Crystal Flower Dangle Choker Necklace

This pretty 1950's 14" choker necklace is made of brass, has a spring ring clasp, and features aurora borealis iridescent prong set crystals. Across the center of the necklace, there are three 1" long dangles with one crystal on the top of a base of six crystals. On each side, there is a dangle with three crystals, and above each of those, there is a single crystal.  The chain has tiny medallion accents. The piece is unsigned, so origin is unknown but is made in the Czech or West German style.  A-1969-1800 fs
