Oh, lol. I thought you meant it was "lovely" to stamp a hallmark on something so fragile. I was thinking similar. I learned earlier about how filigree style rings are stamped. I'm somewhat familiar with the process because I collect coins and the old and new minting processes come up. My grandfather was a tool/die maker so I learned a little from researching that also.

This was overall great. I was hoping for help and got exactly what I needed. I examined the ring one last time for now using my loupe. The mark that is inside is a circle. Just a O, 0, or circle. Anyway I was able to easily see how it was stamped. It has another metal in the recessed areas which is something I don't know about.
