Also known as Hematite.
Hematite was sometimes called bloodstone (not to be confused with the actual bloodstone), as the streak produced by hematite is red and when hematite powder is added to water it can look just like blood.
On top of that the name hematite is derived from the word ‘haima’ which means ‘blood’ in Greek.
