The other day I watched Casablanca on TCM. It is one of my favorite movies of all time. When Ingrid Bergman first steps into Rick's Café, she is wearing a fabulous diamond brooch. I have found many studio stills of the actress and the brooch, but I can not find anything about the origin, designer or current owner of the fantastic piece of jewelry. If anyone has information about the Casablanca diamond brooch, please post.
