Ok, here's the deal. I have a sterling ring that was given to me by a grandparent. It has a fairly large square face that at one time had something on it, but had worn down. A long time back, at the suggestion of the grandparent, I had the surface of the square face smoothed out so that it is a blank square, and had an initial lightly engraved.

It would not make an impression in wax. I have considered having something soldered on that face by a jeweler, it's fairly thin at this point, but I'm still pondering it. That's the only ring I have. Like I said, I very rarely wear it, or any other jewelry.
