This vintage 1960’s brooch measures 2” in diameter. It is mixed iridescent stones, all set in gold tone claw settings. The back of stone settings is open to allow for maximum sparkle. All stones are crystal/glass, not paste-therefore a very radiant piece of costume jewelry. No markings but I am attributing this to Juliana (D&E) based on very similar almost identical styles. Please forward any questions my way!
