This large domed brooch is arranged in three layers. The bottom layer features a row of gold tone scalloped shell pieces. The middle section consists of scalloped pieces alternating with deep green rhinestones and the top level is set with the large unfoiled faceted blue glass stone. This is a rather intricate and heavy piece possibly Austrian or Czech in origin. It is not signed. Some very minor finish loss. Size is 2 inches in diameter with a height of 3/4 inch.
