It is not signed (like much Schreiner) but I have shown it next to the same brooch from Tanenbaum & Townsends Schreiner Masters of 20th Century Costume Jewelry Reference book. This brooch is done in all jet black chatons and navettes in 4 tiers. The bottom tier is staggered in groups of three forming the famous ruffle of this well known brooch. The top faceted stone has one tiny flea bite but otherwise it is in great condition. No missing or replaced stones.
Gold tone is an antique finish with no plating loss. The item "Vintage Schreiner Jet Black Rhinestone Ruffle Flower Brooch Pin" is in sale since Wednesday, June 12, 2019.
