Thanks for taking the time, showing all the very nice good rings and the fakes Gaspare.

Here you buy only the dealer's story (and a bit material).
I's the first fake ground dug of this kind I ever have seen.

Imo the "heavily corroded holes" (the one above and two down ) have more or less the same cut out shape and size, treated with acid .
Originaly corroded it would be more irrigular in this grade of corrosion, but then it would disattrrack the ring.
This last one is really an interesting fake.
