Full Guide To Hematite vs. Magnetite (This Is The Difference)
Hematite (left) vs. Magnetite (right) Hardness . Hematite and magnetite both score 5- 6.5 on the Mohs scale. If you're unfamiliar, the Mohs scale of hardness determines a stone's hardness by measuring how scratch-resistant it is. According to this scale, a stone can scratch any other mineral with a lower score.
