This is a fine amber colored glass necklace. Glass flowers with tiny clear rhinestones continue up to an amber glass clasp. The necklace has fancy amber glass spacers as well. No hallmarks. With a loupe I can see that one flower is broken, but this is so hard to see when the necklace is worn. Many of the clear rhinestones are darkening. Simple push clasp that works fine. Great necklace for any outfit. Lovely color. Length is about 18 1/2". I would date this stunning necklace at c 1930's-40's.
