The Difference Between Hematite, Hematine, and Lodestone

Hematite (Fe2O3) is the mineral form of iron oxide. All natural, even found on Mars.

Hematine, (Ba,SrFe12O19) also called “magnetic hematite, hemalyke or hemalike,” is man-made. Although it is claimed by many that it is made from ground hematite or iron oxide mixed with a resin, analysis has demonstrated it to be an entirely artificial compound, a barium-strontium ferrite. In other words, hematine is not a natural stone. You will not find it at earthegy.

Magnetite, (Fe3O4) also known as lodestone, is a mineral form of iron oxide, similar to hematite, that is naturally magnetic and slightly lower on the hardness scale. Magnetic iron oxides are often used in magnetic storage, for example hard disks, floppy disks and cassette tapes. Lodestone is one of only two minerals that is found naturally magnetized; the other, pyrrhotite, is only weakly magnetic. The name “magnet” may come from lodestones found in Magnesia. It was used for the first magnetic compasses.

The conclusion…if you’re wearing “hematite” jewelry and you can hang a paper clip off it, you’ve gotten the knock off.

I appreciate the concise descriptions and clear comparisons which leave no margin for misinterpretation. The additional information on magnetite was extremely useful as I wanted a natural substance that had the properties of what was called simulated hematite. I was getting the sense that they deal more in the artificial than naturally occurring stones. Thanks for clarifying everything.
