From my collection, this is a Hattie Carnegie pin! It’s shaped like a bridal bouquet of flowers. Measures 2 1/8” long (at longest), 1 ¾” wide (at widest) and back is stamped Hattie Carnegie on an oval shaped disc. Brooch is in very good condition with some very minor white color wear and the pink enamel is missing on two flower petals. The bouquet “stems” have long and short stems – they are not broken long stems. This is a beautiful vintage pin – very difficult to find – and a treasured addition to any collection!
