Hematite is rather variable in appearance and sometimes occurs as black rhombohedral crystals arranged in rosette form (iron roses). It is more frequently found as massive, granular masses with oolitic, concretionary or botryoidal appearance. Hematite sometimes exhibits iridescent coloration. The presence of hematite is often responsible for coloring or staining surrounding material red to reddish brown. Hematite exhibits magnetic properties if heated in a reducing flame.
