A team of researchers from Curtin University, the University of Western Australia, and the China University of Geoscience have discovered that tiny amounts of gold can be trapped inside pyrite, making ‘fool’s gold’ more valuable than its name suggests.

According to the group, this new type of ‘invisible’ gold has not been previously recognized and is only observable using a scientific instrument called an atom probe.
