Red Hematite Quartz is real and natural Quartz that is super loaded with red Hematite minerals. Sometimes called Furruginous Quartz, it may contain a heavy concentration of Hematite, Iron, Goethite, and/or Limonite mineral inclusions. Your ball will be a reddish hue that ranges from orangish-red to purplish-red. Your sphere was born in Brazil.

Hematite Such ore-bodies have been found near Kitchener, B.C. and in the Matachewan area, Ontario. Deposits of considerable size have been found at the contacts of igneous intrusions, generally basic, with crystalline limestone, dolomite, and limey shale; the ore is usually of the specular variety, and it is apt to be partly magnetite.

Iron-oxide nodules or concretions are the most common kind of meteorwrong sent to us. Hematite and magnetite are two common iron-oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron-oxide concretions, iron-oxide nodules, and ironstones are often mistaken for meteorites because they are heavy (dense) and their unusual …

Hematite (hardness 5 1/2-6 1/2) Hematite is a compound of iron and oxygen (Fe 2 O 3) that may be either red and earthy or black with a dull or metallic luster. Both types have a redbrown or Indian-red streak by which the mineral is readily identified. The earthy variety marks paper easily. Pure hematite is rare in the surface rocks of Kansas.
