Hematite
Hematite is a brittle iron ore that is black or rusty reddish black in its raw form but often a shiny black in its polished gemstone form. Hematite is often found on the Lake Superior shoreline, in Iron County, or Houghton County. NASA has discovered that hematite is one of the most abundant minerals in the rocks and soils on the surface of Mars.
