noun
hematite
HEE-muh-tyte/ˈhiːmətaɪt/
An iron oxide mineral that is an important source of iron.
The hematite specimen leaves a rust-red streak on the white testing plate.
Etymology
The blood root gives the mineral its defining image: the Greek expression meant “bloodlike stone.” Its name thus highlights its reddish appearance rather than its use as iron ore or a gemstone.
In context
Artisans ground precious stones into micro powders, hematite for ochre red, malachite for green.
