This is definitely a statement piece.   Measures 2 3/4" x 2 3/4".  It has open back rhinestones and is very well constructed.  The brooch has navette and round prong-set stones in amber / topaz colors.  The brooch is dimensional, multilayered with swirls of gold plated metal interspersed throughout the stones.     This came from an antique dealer's estate sale jewelry.
