Vintage DRGM Schreiber & Hiller Art Deco channel set paste clear rhinestone machine age brooch

Wonderful vintage Art Deco DRGM brooch in silver tone with clear channel set rhinestones using the Schreiber and Hiller company's patented construction. I haven't seen this precise design before and it is stunning. It consists of 'S' shaped flowing leaf-like segments in a long bar brooch design. Made by Schreiber and Hiller in Germany as we now know, these pieces are beautifully and intricately engineered.

The brooch is around 2.75 inches long is stamped DRGM 1139525 on the reverse. The brooch is in very good vintage condition and fastens with a secure trombone clasp.
