Attempted to laser etch my logo onto a silver signet ring. There is a faint outline on the ring, but not enough to see in every light. I used CerMark to make a nice dark etch, but it didn’t show up. The manufacturer says that it works on brass, so maybe I’ll try that.
Cermark makes great laser-etched graphics on steel and aluminum like laptops. Polished sterling silver, not so much.
