Vintage Mid-Century Floral Brooch Featuring Aurora Borealis Rhinestones

The design on this sparkling brooch is a floral spray or leaf cluster, which was a classic mid-century botanical silhouette.
The metal is a textured gold-tone finish.
The stones are glass rhinestones with an Aurora Borealis coating, a unique lustrous finish that reflects a dazzling rainbow of colors, including blue, green, and gold, depending on the light.
Era: Circa 1950s–1960s.
The piece is in good vintage condition with some patina only on the pin part on the back of the brooch. Please see photos.
