I bought this ring off of ebay almost 10 years ago. It was sold as sterling but I see no marks on it and it's never needed cleaning even with daily wearing , it retains the shine amongst the antiquing. I was drawn to it because it looked like reptile skin wrapped in rope and was so unique. The domed part is hollow and has a small nub on the inside, maybe from a molding process? And the back of the band has a slight buckle, perhaps from being resized at some point. I would love any additional info people may be able to provide, I was so pleasantly surprised at everyone's amazing insight on the last mystery ring I posted. Thank you in advance, you all are awesome!
