Ring?

[Garabaldi]

I have found a Mexican silver ring with patina just like this before. Do you think this is a ring and if so is it silver?

I am including an image of a silver ring I found at the same site. They look like the same material. The ring I found today does not have any mint marks inside.

Some Mexican silver is not 90%, so your ring is a possible. I'm not expert enough to be certain.

Your other ring is definately sterling silver, thus the marking 925 (= .925 fine, or 92.5% silver).

I would say it's a ring, and could be silver or silver plate. The green is where it was brazed together. Tony
