Clever indeed, and a few nights ago I turned the Internet inside out looking for another example. Got nothin'. I will come back and post if a clue turns up--they almost always do!!

I haven't handled any Rice-Weiner/IndoCraft (sadly--what I wouldn't give to thrift a Thief of Baghdad piece!), just looked at a lot of pictures, but it all looks a lot heavier than these are in person. They're super thin and delicate, and are much closer kin to the bracelets you posted. I don't have a testing kit but they tarnish, polish and smell like silver, and 'feel' Czech or Austrian.

Let us know if you made this one yours and got to pick it apart a bit more!!
