The thing about this pattern is that they're so heavily forged. If you really wanna make sure you get an authentic one then get a good one with clean details and less flaws. Laurin is a quality stamp.

IMO
The ring with rust on it is a no for me, .835 silver doesn't turn into that color unless it's been compounded with iron. And the ring that has the black dots above the silvermark is also a no for me, looks like it's been casted and not stamped. .835 silver is pretty sturdy, I can't find any reason for it to get those markings in that spot for wearing it or if it just been laying beneath the earth.
