>>9781882I used a two-part epoxy putty called Milliput for the ring. Admittedly a strange medium to fashion a ring in, but it was the only thing I could think of that would be strong enough to be worn and that I could sculpt like a clay.
It was still a bit delicate though, and not really something that could be worn every day. Smithing with some malleable metal would be a much smarter way to go, but once I had gotten the idea in my head, I was a bit impatient to see a finished product. :)
