For sure a cool looker, but a not very professional made casting.
And for me for sure not period in Norway made.
This Norway made rings are to nearly 100 % at least a two piece
construction with soldered on plate and have a typical hallmarking.
Definitely cast, and the design is nothing I've ever seen before, leading me to believe that the design is a fantasy design. There were more than a few Viking ship design Norway rings, but this is unseen by me. It would be nothing that I would invest money into.
"Much that once was, is lost. For none now live who remember it."
Okay, thank for the education guys! So it looks cool but are not worth the 1220 USD the seller wants for it :P
I hope that it doesn't fool anyone else than me.
I will post the last ring from this seller tonight and see what you have to say
