Beautiful and Unique Gothic Look Necklace and earrings set-Stunning

Beautiful stunning necklace set perfect or a Grad or a formal event. Just beautiful and very detailed. Amber rhinestones line the chain, which I believe may be copper or brass, although I believe it may be too light to be full on brass. Large amber stone in oval setting. I cannot find any makers marks on it at all, but in all sincerity, I don't know why anybody wouldn't want to mark this beautiful piece. Very unique and classy. Have looped it and used my magnet on it and it does not stick to it. No marks found by myself. 16" chain with pendant adding 1 1/2 inch drop at center 8"
