Prong set and open backed Green Navettes surround Aurora Borealis "flowers" in this 2 1/2 " Circle Brooch. Each AB "flower" has a large faceted chaton in the center, surrounded by smaller ones. The soft light diffusing through the open backed green navettes, contrasted with the iridescent chatons, creates a fresh "watery" look. The pin back remains shiny and unmarred and the long pin on the back secures with a roll over clasp. This quality made brooch is in Excellent Condition.
