Thorite. This is a very rare thorium mineral. Not much to look at, but it has a well-defined crystal structure and it's hot enough that when it fell under a bunch of stuff, I had no trouble locating it with a Geiger counter. (This is one of the great advantages of radioactive things: You can never really loose them. Not so the osmium pellet I'm probably never going to find.) The price reflects the rarity of this species.
