I can not find the makers mark anywhere but this ring is an exact style of a Hansen ring from the 70’s. It very well may be a Hansen, but I have no idea. I didn’t polish it on the wheel as I do not want it looking new. Im guessing on the size, I wear a 6 on my right ring finger, and it’s a tad loose. Only fine wear marks, perfectly round and taken care of. I would greatly appreciate if anyone knows this makers mark messaging me on here. Thank you for looking! Photos are the main description for this piece. I believe this is a special piece!
