This vintage trembler brooch is an amazing creation! It is a multi-layered confection of goldtone leaves and flowers, embellished with rhinestones. Please take a good look at my photos to appreciate the intricacy of the design and the hand-wiring of the various elements. The top rhinestone flower is attached via a metal spring, hence the "trembling" element. The dealer that I purchased this brooch from thought it might be french. To me, it also has a Miriam Haskell look to it. Nice condition. A few of the rhinestones have started to darken, but this does not detract from the beauty of this piece.
