Hematite. A dark-colored, shiny stone, hematite gets its metallic, mirror like sheen from the iron that is its main component. In its natural state, hematite's iron content is covered in rust, earning its name, which comes from a Latin phrase meaning "blood stone".
The Banded Hematite Jasper Formation within the Iron Ore Supergroup of the Singhbhum Craton in eastern India comprises fine alternating layers of jasper and specularite. It was deposited at ∼3000 Ma and deformed by a mobile episode at ∼2700 Ma.
Genesis Stone / Banded Iron Genesis Stone / Banded Iron is a sedimentary stone made of alternating layers of jasper and hematite or magnetite. It was formed 1.8 - 2.4 billion years ago in the ancient iron seas. These pieces were broken off from the main formation by an unknown event and left to weather on the Wyoming plains.

Banded Jasper w/Hematite Natural Chunks (South Africa) - These South African Banded Jasper with Hematite Natural Chunks have an earthy reddish hue, bands of Hematite, and are just beautiful. They would be a wonderful addition to any collection and can even be used in the garden.
Banded Iron Formation ... The red jasper or Tiger Eye makes a wonderful compliment to the sparkling silver gray of the hematite. The banded layers, sometimes contorted by ages of folding and faulting, make for surreal landscapes of asymmetric bands.
A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor shales and cherts, often red in color, of similar thickness, and containing microbands (sub-millimeter) of iron oxides.
Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores The Open Mineral Processing Journal, 2011, Volume 4 47 consists of hematite and quartz as the major minerals.

Banded printstone jasper is for increasing your creative drive, stability, wisdom, and a connection to Mother Earth. Brecciated jasper is a jasper that can be veined with hematite. It is and excellent aid to keeping your feet on the ground and achieving emotional stability.
Abstract. The separation of iron oxide from banded hematite jasper (BHJ) assaying 47.8% Fe, 25.6% SiO 2 and 2.30%Al 2 O 3 using selective magnetic coating was studied. Characterization studies of the low grade ore indicate that besides hematite and goethite, jasper, a microcrystalline form of quartzite, is the major impurity associated with this ore.
Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age.. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron ...

For example, jaspilite is an attractive reddish & silvery gray banded rock consisting of hematite, red chert ("jasper"), and specular hematite or magnetite. Because of their age, most BIFs have been around long enough to have been subjected to one or more orogenic (mountain-building) events.
Red Yellow Hematite Jasper is distinguished by the colour banding interwoven with Hematite. Metaphysical Properties Red Yellow Hematite Jasper is an excellent protection stone, providing protection for both travellers and astral travellers.
