Rare 1980s Ciner signed enamel conch shell crystal gold tone brooch

This is an absolutely gorgeous and very rare 1980s signed Ciner enamel conch shell crystal gold tone brooch. The enamel is salmon pink. The Swarovski crystals are on the tips. Signed Ciner on its back. Measures 3.0 x 2.0 inches. There is a tiny bit of gold plating tarnish on its top which is barely visible (please see all the pictures), other wise in excellent vintage condition.
