Rainbow hematite is a form of hematite, a common iron oxide mineral with the chemical formula Fe2O3. What sets rainbow hematite apart from typical hematite is its captivating iridescent or rainbow-like sheen. This iridescence is caused by the presence of a thin layer of microscopic platelets or scales on the surface of the mineral.

Hold a piece of hematite in each hand, close your eyes, and take three deep breaths. As you breathe, visualize yourself as a tall, strong tree. See the roots of the tree—a few inches in diameter—growing from the sole of each foot and spiraling down into the core of the Earth to create a solid foundation.

Check for Magnetism. Real Hematite is very weakly attracted to magnetic fields. This magnetic attraction is not strong enough for a magnet to even lift the mineral off of a table. Being very weakly responsive to magnetic fields, hematite cannot be used as a magnet. However, you might find strong magnets being sold in shops under the name ...

Starting with hematite, it's made up of iron and oxygen, with a specific formula of Fe 2 O 3. That means that for every two iron atoms, there are three oxygen atoms hanging around with them. Now, magnetite's formula is a bit more complex. Its formula is Fe 2+ (Fe 3+) 2 O 4.

Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight.
