Interesting to read this, thanks for sharing these links, Paul.
It points out, of course, that when anything is "really highly unusual", it needs to be examined with an extra critical eye.  " Extraordinary claims require extraordinary evidence" (Carl Sagan) and, " Anything that sounds/looks too good to be true, probably isn't" [a good precept to remember, particularly when buying mineral specimens!]
