    All of the rare earths except promethium(Pm) occur naturally along with scandium(Sc) and yttrium(Y) which are not rare earths but are normally found in the same ore deposits. The rare earths are not rare. They are just unfamiliar to most people. As an example of their abundance, lutetium(Lu) is 200 times more abundant than gold(Au).

    The lanthanides are sometimes called the rare earths, a name that dates to the 18th century and misleadingly suggests that their abundance is low. At present, the world reserve of rare earths is estimated to be about 150 million metric tons, in the form of rare-earth oxides, while the annual consumption is only about 120,000 tons.
