This is an unmarked Asian Princess mask fur clip by Reinad. They did several versions of this style of brooch.. some with pave set rhinestones and examples like this that have an enameled face. She measures 2 1/4" high by 2" wide and is embellished with emerald green, ruby red and diamante rhinestones. It looks like one of the ruby stones is darker and can easily be replaced with the correct color. Her lips are enameled in the inside opening which was typical of Reinad and lends an interesting three dimensional effect. She is very much the epitomy of Art Deco jewelry. This one has seen the years go by as there is some enamel loss to the green paint. Still an interesting and worthwhile piece to add to your collection. It is considered a book piece and is really impressive when worn. I have priced it accordingly as these usually sell for $500-$1000!
