Czech Glass Rhinestone Necklace

Czech glass collar necklace unsigned but believed to be by Lilien.  Large dark amber and purple faceted prong-set Czech glass with clear rhinestones bordering around.  Two thin rows of rhinestones connects the 9 individual settings together.  Hook clasp does not appear to be original.  We would wear with a camel high neck sweater, camel wide leg pants and white Converse.  Dark amber, purple, brass.
