This lovely shell cameo has a twisted rope edging. The cameo itself is very pretty. The woman has an elaborate coiffure and a draped neckline with a flower. Chain is about 18 1/2" long. The cameo is 1 5/8" including the bale. I can't find any markings on the metal but I am quite sure that the Simmons chain is gold filled. This necklace is in excellent condition.
