Magnetic Hematite Vs. Hematite Mineralogy Geology

2021-7-12  Polished mineral hematite and magnetic hematite are visually very similar. It is easy to confuse the mineral hematite with the man-made material that goes by the name "magnetic hematite." In certain forms, both share a very similar silvery appearance. In addition, both are often confused with the mineral magnetite.
