Pyrite and Hematite: The Differences. In terms of hardness, pyrite is slightly harder than hematite. When comparing the Mohs scale for mineral hardness- which ranges from one to ten with two being as hard as a fingernail and ten being as hard as diamond- pyrite falls between 6-6.5 on the scale, while hematite falls between 5.5-6.
