Vintage Aurora Borealis Layered Cluster Brooch with Rivoli and Margarita Stones

This beautiful mid-century brooch layers fancy Rivoli and Margarita stones and achieves a truly breath-taking sparkle of color. The stones have been given an aurora borealis coating, so in addition to the main soft yellow color, the brooch flashes with pinks, blues and greens. The brooch is 1 3/4 inches in diameter and has no maker's mark. In excellent condition.
