I'd like to see clear photos of them, but, from what I Can see of the 3, they are looking okey-so far.
"Much that once was, is lost. For none now live who remember it."
3 period existing patterns, but very good fakes of this rings are around.
Clear pics are the key in this case.
Originals of this patterns are die struck, any sign of casting (for example pittings)
are killing them.
Without very good pics i wouldn`t buy them.
On this example pic i am nearly to 100 % sure a cast fake ring....casting pearls and pittings
