  Odd-shaped lump. 
This irregular lump comes from Tim Worstall, the world's leading expert on the scandium  and scandium oxide trade by virtue of the fact that he is about 60% of the world's scandium trade. (Some day I may actually have some scandium from him, but for convoluted reasons, at the moment I have a couple of other rare earths instead.)
