Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. 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 (Nadin, 2007).

Iron forms both $ce{Fe^2+}$ and $ce{Fe^3+}$ ions.The first combine with oxygen ions to $ce{FeO}$; the second $ce{Fe2O3}$. $ce{Fe3O4}$ can be thought of as a mixture of both compounds in equal amounts. So $ce{Fe3O4}$ contains both Fe(II) and Fe(III) ions; twice as much Fe(III) as Fe(II).. In the picture below, showing the crystal structure, green atoms are Fe(II) and brown atoms Fe(III).
