Small crystal, 99.999%. Kindly donated by David Franco, who sent many elements after seeing the slashdot discussion, and this one after I sent him some Mathematica t-shirts. This is a nice example of a hopper crystal. Not as big as our other samples, but much more pure of course, since it came from David.
