Putting the ring in a sealing device wouldn't work; I would like to be able to wear it. I've tried painting it with black nail polish and with clear coat; they've both rubbed off pretty quickly. I did find a link detailing how the author used to cast things as a kid- I think I'm going to try that. (I can post the link allthough I'm not sure how to insert it.) I'm just not sure what the best metal to use would be. I don't really have the resources to make a crucible or anything; I've been offered the use of a beer brewing camp stove type thing by a relative, which seems promising, but I'm just concerned about melting the pan we use to melt the metal, so it can't be too hot. Gold would be nice and durable, but maybe a bit overkill for what originated as a crappy costume ring. Zinc is what the link suggested, so that might work, but I'm leaaaning towards sterling silver. Any tips for this are appreciated. I probably won't go casting house unless they can do it under 200 (doubtful) but I'm a little worried about this method.

There are all kinds of breakthrough advances in scanning for 3D reproduction, and the technology to do this is becoming less and less expensive. We are beginning to see the commercial application of this scanning technology in everything from video games to action figures. In their lab, he's able to scan just about anything (as long as it's no bigger than 8 inches or so) and replicate a duplicate of it (albeit in plastic) on the 3D printer.
Perhaps there would be a local university where the engineering or physics majors might do you a favor and scan your ring, leaving you with a CAD file that is an exact representation. Once you've got that, it's simple to print a plastic version of your ring. From that, you might make a mold out of slip clay, and then melt (or burn) the 3D printed replica out of the mold to leave you with a mold to pour brass or some other softer metal.
If you've ever seen people do lost-wax casting, it's not that hard to do. Brass melts at a relatively low 1700 f. Aluminum melts at 1200. Either of those would be (relatively) easy to work with.
