I don't have the address handy, but I can get it for you. There's a
guy who advertises in just about all the trade magazines that he
supplies replacement stones for antique rings, little triangles,
scissor cut baquettes, etc.. He's out of Hollywood, Florida, so you
can't miss his tiny ad in the back of the mags. If you don't find
him, I'm out of town for a week, but email me and I'll look it up for
you when I get back.
