Help With Identification "NN" Possible Niels Nielsen Ring?
Posted: Wed Jan 21, 2015 3:42 pm
Hello! I have a blue pyrite ring with which is marked "Sterling NN." The NN is inside of a 6 sided diamond shape, and I believe it could possibly be Niels Neilsen, but I am not sure. I have supplied a picture of both the ring and the hallmark as a reference.
