This stone, also called hematite, acerine and oligist, is the mineral form of ferric oxide. The chemical formula of hematite is Fe2O3. This mineral is crimson red and when washed it stains the water. The dark gray color predominates, the stone is almost black, but internally carmine red shines. It comes in two varieties, specular hematite and earthy hematite. Its structure has inorganic materials such as: (titanium (Ti), aluminum (Al), manganese (Mn) and water (H2O)).
A little history
The Greek Theophrase called it haematitis lithos (blood stone), approximately in the years 300-325 BC.
It is said that this mineral was formerly generated through the blood spilled by warriors, in the battles that took place centuries ago, that was what Theophrastus believed.
Main characteristics of hematite
Its material is hard, surpassing iron for its hardness, but it is not very resistant, its brittleness is 5-6 on the Mohs scale, its density is 5.27 gr / cm3.
An intense red streak shows in the hematite when it is finely cut, this main feature is the one that differentiates it from the goethite that presents a yellowish brown; the magnetite who presents it in black and the pyrolusite that presents a bluish-black color, if these stones are cut.
Hematite has two unique characteristics that differentiate it from galena and magnetite, these are the lack of exfoliation and magnetism.
It may be of hydrothermal origin, they are found in metasomatic deposits , this mineral is incorporated in igneous rocks or they can also be produced by weathering
Properties of hematite.
The red color with ocher masses, dark gray and silver gray, are those that characterize this stone, they present the stripe crimson red color; It also has silver gray and black crystals.
The shine that this mineral presents is metallic, sub-metallic and earthy. If light is reflected from this mineral, they take on a white or grayish white color, with a bluish tint and reflections of deep red or blood. This mineral can be dissolved in hydrochloric acid slowly.
In its pure state, hematite contains 69% iron, and also contains traces of water, manganese, titanium and aluminum.

Varieties of hematite.
Specular hematite or specularite : which has a silver gray color with a metallic to submetallic luster, they are shown as small mirrors, hence their specular name derives, the alteration of pyrite and magnetite produce this mineral. It appears in tabular or leafy habit or as anhedral crystals.
Earthy hematite : it is reddish in color, stains the skin when touched and stains the water when washing. White and transparent crystals are observed in this variety, which can be calamine, hemimorphite and smithsonite, which are zinc minerals. These components are identified through treatment with hydrochloric acid. The solubility of hematite can be observed with this treatment and the color that is generated is yellow.
Main deposits of hematite.
The places where the deposits of this mineral are found are: Grishun in Switzerland, Elba Island, Tuscany in Italy, Piedmont and France. Also in towns in Spain such as Zaragoza, Granada, Asturias, and Seville.
Deposits in Myanmar and Nigeria stand out at the gemological level.
Different uses of hematite.

Care and cleaning of hematite.
This mineral is very soft, tends to have a brittle toughness. Its care must be equal to that of apatite or opal. Do not use ultrasonic cleaners or sprayers.
Avoid using cleaning fluids, bleach, or acid as they are aggressive chemicals.
To clean this stone, it must be done by moistening a soft cloth with warm soapy water (use a mild soap). Then rinse the stone very well, making sure to remove any soapy residue.

If you are going to do vigorous physical activities that make you sweat a lot, always remove your jewelry, to avoid getting damp with body sweat.
It is said that the red color of Mars is due to its composition of materials that have been exposed to traces of oxygen and water vapor, present in the atmosphere of that planet, which form iron oxide, the same component of hematite.
Red rust is the mineral that predominates on Mars, this material is very similar to hemetite, it even shares the same chemical nomenclature, but its physical structure is different.
One of the differences that stand out are that the hemetite has large crystals like sand, while the red rust is powdery, fine, and only a few hundred nanometers in diameter.
