Green Satin Rhinestones Flower Brooch Vintage Pin Austria ?

Beautiful vintage sprawling floral brooch featuring pastel green and white frosted glass cabochon stones and green iridescent aurora borealis rhinestones. I love the unusual freeform design and pretty colors, especially the contrasting enamel inside the four little flowers. Bright gold tone metal reminds me of Austrian jewelry, but it's unmarked. nicely made and in good vintage condition with no issues. 1 3/4" x 2".
