Saffron – $15 per gram. Saffron is not even close to being one of the rarest things on Earth; still, it is making an entry in our list. The reason is that it grows in the middle of a crocus flower, which is an extremely labor-intensive crop. Around one acre of land of purple crocuses yields only one pound of Saffron.

Most REEs are not as rare as the group's name suggests. They were named "rare-earth elements" because most were identified during the 18th and 19th centuries as "earths" (originally defined as materials that could not be changed further by heat) and in comparison to other "earths," such as lime or magnesia, they were relatively rare.

The rare earths are of a group of 17 chemical elements, several of which are critical for the energy transition. Neodymium, praseodymium, dysprosium and terbium are key to the production of the permanent magnets used in electric vehicles (EVs) and wind turbines. Neodymium is the most important in volume terms.

A single smartphone contains approx. 8 different rare earth materials. Rare Earth Elements are not rare in the earth's crust – but they're rarely found in commercial concentrations as they are in the Mt Weld deposit. Rare earths make cars greener – Cerium (Ce) is used in catalytic converters to reduce exhaust gas pollution.

Rare earths are also used as a refiner in gas used to fuel internal combustion engines. Rare earth magnets, like that of Neodymium-iron-boron, are used in sensors, and even ferrite magnets contain small amounts of rare earths and minor metals like Lanthanum and Cobalt to improve magnet performance by as much as 25%.
