Pyrite has a higher specific gravity measuring 4.8-5.0, while gold weighs in at 19.3 g/cm3. Even though gold has a higher mass, pyrite's relative density exceeds that of gold due to the presence of sulfur in its molecular structure. So by volume, a piece of pyrite weighs more than the same volume of gold.
