Unmarked D&E Style Rhinestone Leaf Brooch with LIght Sapphire Satin Finish Navettes and Pear Cut Stone

This is a lovely Unmarked brooch in the D&E style with light sapphire satin finish navettes and a light sapphire pear cut stone. The small chatons are topaz ab. The pin is 2 3/4" long in rhodium plated silver tone metal. There is one small chip on the rhodium plating on the back of the pin. I believe this is the work of DeLizza and Elster from the 60s. It is stunning.
