Vintage Art Deco machine age geometric gold tone brooch with moulded Peking glass green stones, trombone clasp French or Jakob Bengel ?

Fabulous large Art Deco 1930s machine age geometric brooch with gold tone and two curved pieces of moulded Peking glass in a vibrant green. This stunning piece shows a wonderful geometric, streamlined style from the 1930s Art Deco period. The piece feels beautiful when handled - high quality and smooth. It is beautifully engineered and fastens with a secure trombone clasp and pin. The clasp suggests it may be a French brooch but it also has features seen in pieces from the Jakob Bengel factory in Germany. The brooch is in very good vintage condition.
