Try a streak test. Magnetite, Hematite, and Meteorite all have slightly different shades of brown to reddish brown in color to help identify. This way is not full proof though because there are earth minerals like Goethite that are a mix of iron and other minerals that streak like a meteorite. Plus Goethite can also be found in meteorites too. I would agree with Terry on this one if you really wanted to know though!
