I just bought this chain at the retailer. I used my tiffanys cleaning cloth and it was so dirty the cloth got black and some of the grime was on my hands. Maybe this chain was sitting too long on the shelf or in the safe because the stores been closed for a while. After I cleaned it the chain shined hard., I kept on cleaning it and it was still showing black on the cleaning cloth not as much. Nothing wrong with the chain maybe gold attracts dirt easily. I'm still satisfied with my chain. I haven't worn gold in years.
