Great combo! Flashy AB (aurora borealis) coated blue-green navette rhinestones, alternating with unfoiled deep blue navettes, frame a core of filigree clustered daisies, each set with a center green rhinestone. A curling stem set with AB chatons completes the leaf pattern. Most likely from the 1960s; excellent condition, unsigned. Measures 2.25" across, as shown in the first picture (with the pin stem horizontal).
