AeroGel, It cost About $300 billion per milligram.
Just a comment here: That is debatable. The very chemical composition of AeroGel makes it about 99% air. That means its actual mass at that weight (1 milligram) is considerable. If you are going for "most expensive material on earth" by actual amount/size/mass, it's probably antimatter. Again, debatable. Oh, almost forgot: the last time I did any research on this, antimatter (especially antiatoms like antihydrogen), were at $1,750 trillion US Dollars (USD) per ounce.
