I took Steel wire, big buffalo horn disc and a cowrie shell and turned them into a ring. If your fingers swell I would not suggest wearing this ring as it does not have the give of precious metals.
The steel made up into a nice ring and takes a pretty good polish. I wanted to do some very large pieces and since I had these 2 inch horn discs it seemed the perfect opportunity. The shell is 7/8 of an inch. I made earrings and pendents with the horn discs. I will photograph them and get them posted.
