Magnesioferrite is a magnesium iron oxide, and a member of the spinel group. It forms a solid solution series with magnetite. Rammelsberg (1859) originally described this species from Mount Vesuvius (dubbing it magnoferrite). Later, Professor E.S. Dana recast the species name as magnesioferrite in his 1892 System of Mineralogy using the neo-Latin root magnesio for magnesium and the historic root ferrum for iron.

This specimen consists of magnesioferrite crystals growing on a phlogopite matrix. The largest magnesioferrite crystals measures 5 mm on edge. This is a large rich specimen. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
