Vintage Schreiber & Hiller (unsigned) flower brooch, Art Deco channel set red, pink, orange, yellow, blue and clear paste rhinestones

Vintage Art Deco brooch unusually in gold tone with red, pink, orange, yellow, blue and clear channel set rhinestones using the Schreiber and Hiller company's patented construction. I haven't seen this design before and it is so unusual.

The brooch is just over 2.5 inches long and 1.5 inches wides. It is in very good vintage condition and fastens with a secure roll-over clasp and pin.
