Most Expensive Materials in the World — There are several
extremely expensive substances in the world, and all of them have to do
with exotic physics. Historical contenders for the most expensive
substance such as saffron, plutonium, gold, and diamond are like dirt in
comparison to these. Three categories of material that compete for the
most expensive substance are antimatter (especially anti atoms like anti
hydrogen), at $1,750 trillion US Dollars (USD) per ounce, followed by
hafnium and tantalum isomers, at about $480 million USD per ounce, and
assorted exotic particles such as bottom quarks, which are in the same
league as antimatter.
