DeLizza and Elster aka Juliana Emerald Ribbed Ovals with Emerald Navettes with Filigree Metal Accents

This is a lovely pin with ribbed back carved ovals in emerald with emerald navettes and a filigree leaf on top of each oval. It is in like new condition. I can attribute the topaz ribbed stones to Juliana DeLizza and Elster and the between stones is all a characteristic of their work. The pinback is also a style they used . I think it is gorgeous. The pin measures 2 1/4x 1 1/2". It is not marked.
