I find Black and brown hematite, I even have some that has a red tint to it ,like blackcherry.. Some hematite is more dense than others. I would bet anything that its hematite, I only have a couple hundred pieces of the stuff. I am not saying that those are not plow dings, but I am saying the piece was used due to the polish on it. OK that's my final opinion. John P.s I have always believed that hematite was Iron ore. Whats the difference, between Ironstone, and iron ore?? If you were to rub that stone on another, you should get a red powder.
