Handmade brass necklace with what I believe from research and testing to be amber. The stones glow under black light as seen in the photos. The brass has been wiped down but it does show natural patina. The stones have some residue which I will let the new owner clean. It has been wiped down but I do not want to try to clean or buff it as I am not a professional. I just wanted you to be aware before purchasing. Please see all photos as to the condition of the piece, they are part of my items description. The cord is a suede with a 925 sterling lobster clasp.
