=== Crystal size and morphology === Chromite occurs as massive and granular crystals and very rarely as [[Octahedron|octahedral]] crystals. [[Crystal twinning|Twinning]] for this mineral occurs on the {III} plane as described by the [[Crystal twinning#Common twin laws|spinel law]].<ref name=Mindat /> Grains of minerals are generally small in size. However, chromite grains up to 3 cm have been found. These grains are seen to crystallize from the liquid of a [[meteorite]] body where there are low amounts of chromium and oxygen. The large grains are associated with stable [[Supersaturation|supersaturated]] conditions seen from the meteorite body.<ref name="Fehr-2004" />
