Brooch Vtg Large Rectangular Rhinestone w an Array of Colorful Rhinestones

This is a gorgeous, large unsigned vintage 50s brooch in a gold tone setting. A large, rectangular, faceted green rhinestone is the main centerpiece. It is surrounded by small aurum chatons that give off warm blue highlights. The next row has light blue, AB, and darker blue navettes with green chatons on the corners, forming a floral or burst-like arrangement. All the rhinestones are prong set. The brooch has a vibrant and eye-catching appearance due to the contrasting colors and sparkling rhinestones, making it a statement piece of costume jewelry. Given its age, I would say that it is in great vintage condition. The only thing I see is that one of the green corner chatons has darkened just a little, not noticeable.
