It may be small but it packs a punch.

I was doing some reading about plutonium and realized that I have a desire to own a thing that's surprisingly heavy when picked up. Deceivingly so. Heavy enough to make people exclaim at the weight of my small object. Bonus points if it's not (too) poisonous or (very) radioactive. I know Au and Pb are pretty heavy, but can I beat that? What's the very densest thing I can (legally) afford to acquire in sufficient volume to keep on my desk and fidget with?
