To be honest with you, I think it is. I have checked it for markings of the metal merit, and I can not find anything on it to indicate that it is real.
But it still is a pretty necklace, especially for those who wont have an irritation to it. I have also been told that those with sensitive skin can coat the fake stuff with a clear nail polish, to both preserve the luster of the metal longer and reduce/ or even completely take away the skin irritation entirely. Hopefully all of the information that I have provided has answered your question. Thank you for your interest.
