3D3DLump with interesting surface. 99.95%.
Ed ordered this lump just because he heard it was the most useless element. I suppose that says something about Ed, don't you think?

I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
