How to Tell if Hematite is Real or Fake in 6 Easy Ways
One way to identify such poor-quality rocks, which may otherwise compositionally still be close to Hematite, is to check their density. Hematite is a very dense mineral. This means that it is considerably heavier as compared to other minerals of the same size. It has a density of 7.9 g/cm³ at room temperature.
