Rare earth metals are critical to high-performance optics and lasers and key to the most powerful magnets and superconductors in the world. Rare earths are simply more difficult to mine than most metals and generally don't accumulate into rich ores. This rarity, combined with the demand for the metals in high-tech applications, brings about economic and political complications that make some of the most interesting metals even more exciting.
