Mellon, I think what's
really confusing me is that your "for" argument could just as easily be an "against" argument.
See, if you're going to take the "indeed there could not be two such gems...even in all the world"
literally, (as if it were, oh, I don't know, given under oath or something
), then I should say it completely
demolishes the Silmaril-Arkenstone case through simple arithmetic.
Wish I'd thought of that one!
