Jewelry supplies (text only, sorry)

Anyone know where online I can find a solid wire hoop necklace? Like this except with no pendant. Just a plain silver hoop.

All I can find so far is memory wire, and that's not exactly what I'm looking for. I'm looking for a looser hoop.

Or even if I could find heavy enough wire that would hold it's shape and not bend if used in this manner. I don't know what gauge that would be.
