Designer Carbon Materials, an Oxford-based scientific startup, has recently sold its first 200 micrograms of nitrogen atom-based endohedral fullerenes for 22,000-or about 110 million per gram.

This valuation likely makes the material the second most valuable on Earth, preceded only by antimatter, which is estimated by NASA to cost some 41 trillion per gram.

The material, which essentially is a cage of carbon atoms with a nitrogen atom inside, could be used for very small and very accurate atomic clocks, which are currently of the size of a room.
