Hematite is a mineral that is common and can be found almost everywhere in the world in volcanic rock. The mineral has a hardness between 5.5 and 6.5 on the Mohr scale. Hematite has a high iron content and can therefore be made magnetic using a magnet. Magnetite is also found all over the world and has the same hardness as hematite and, as the name suggests, is also magnetic. Therefore, as now, it is not possible to say which mineral it is.
