Magnetite is an important iron ore, along with hematite.  Nanoinclusions of magnetite crystals cause the iridescence of Rainbow Obsidian (Nadin, 2007).  Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen.

Magnetite is a natural magnet, hence the name, giving it a very nice distinguishing characteristic. Explaining the magnetism is not easy but here is a go at it. Remember, electricity produces magnetic fields just as magnetism produces electric fields.  Magnetite is a member of the spinel group which has the standard formula A(B)2O4.  The A and B represent usually different metal ions that occupy specific sites in the crystal structure.  In the case of magnetite, Fe3O4, the A metal is Fe +2 and the B metal is Fe +3; two different metal ions in two specific sites.  This arrangement causes a transfer of electrons between the different irons in a structured path or vector.  This electric vector generates the magnetic field.
