Poster sample.
This mineral, Aeschynite, appears in my Photographic Periodic Table Poster representing neptunium, because this highly unstable element can't reasonably be photographed. The rock probably contains on the order of a few atoms of neptunium at any one time, as part of the complex decay chain of the uranium that makes up a much larger fraction of the sample. In no meaningful way is neptunium itself visible in the sample, but sadly that's about the best you can do with an element like this. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
