University of Minnesota''s Mineral Pages: Hematite

Some hematite samples, however, do contain enough magnetite that they are weakly magnetic, so it is always a good idea to check a magnetic sample''s streak by scratching the sample across a white ceramic plate. Hematite will leave a red to redbrown streak on the plate, while magnetite will leave a black streak. Ilmenite
