Hi Wayne, I don't think I've heard of black silver. I guess this
different than sterling silver that has been oxidized/sulfurized
since the color goes all the way through. If it is, what is the
composition and how else does it differ from sterling (maleability,
hardness, etc.). Thanks for any you can provide.
And thanks to everyone else that has participated in this thread.
So many interesting possiblities have been mentioned that this is now
turning into a quest for new metals to work with rather than just an
idea for one ring!
