Osmium

Element #76 with the symbol Os, a.k.a. the bluest metal in the world. Although it might seem pretty, Osmium is far from being good jewelry or building material, unless you want things with unbelievably high costs. It's a relatively non-toxic substance, granted that you don't combine it with Oxygen. Its name comes from the Greek word "Osme", which means "smell", "scent", or "odor". This definition refers to the nasty volatile compound that occurs when you mix Oxygen with the latter. It's also an extremely heavy metal, weighing 5x more than Lead does.

Osmium is the heaviest, stable metal in the universe.
