 (hē′mə-tīt′)
n.
A black or blackish-red to brick-red mineral, essentially Fe2O3, the chief ore of iron.

[Middle English emathite, ematites, from Latin haematītēs, from Greek (lithos) haimatītēs, bloodlike (stone), from haima, haimat-, blood.]

hematite

(ˈhɛmətaɪt) or

haematite

n
(Minerals) a red, grey, or black mineral, found as massive beds and in veins and igneous rocks. It is the chief source of iron. Composition: iron (ferric) oxide. Formula: Fe2O3. Crystal structure: hexagonal (rhombohedral). Also called: iron glance
[C16: via Latin from Greek haimatitēs resembling blood, from haima blood]

(hē′mə-tīt′)
A reddish-brown to silver-gray mineral consisting of iron oxide. Hematite occurs in igneous, metamorphic, and sedimentary rocks and is the most abundant iron ore. It is usually slightly magnetic.
