I actually was thinking of keeping it in a sealed lead lined box as one of my many curiosities.
I can just imagine people going: what's in that box? and me going: Oh! it's just a block of depleted Uranium. You wanna see it?
And then get to see people think that I'm totally insane for keeping a thing like that in a box but be too curious not to take a look at it.
Thing is I have a knack for strange materials and minerals... it's something I take from my grandmother.
In my rarities, I also have a small aluminum ingot, a lump of coal from Alberta, countless crystals, some quartz, some agates, a few sand roses, some mica, all sorts of sea shells, a few corals that date back to the 1950's, a conch horn, a Coolidge tube, some high voltage ceramic insulators, turbine engine blades, a polydactyle ceramic hand and countless other things. Usually the stranger the better... As long as it allows me to tell an interesting story, it's fair game.
I once wanted to buy a dry box fish but mom stopped me... granted the eyes on that thing weren't glossy anymore and it had seen better days.
