Collection: Hematite

Hematite is a well-known mineral, composed mainly of iron oxide (chemical formula: Fe₂O₃ ). It is one of the main sources of iron on Earth and has been used since ancient times, as much for its metallurgical properties as for its symbolic and decorative virtues.

🔬 Physical and chemical characteristics

• Chemical formula : Fe₂O₃

• Color : metallic gray, black, brownish red

• Shine : metallic or earthy

• Streak (powder left on a plate): reddish-brown — this is one of the best ways to identify hematite.

• Hardness (Mohs scale) : approximately 5.5 to 6.5

• Density : relatively high (~5.3)

🌍 Origin and deposits

Hematite forms in different geological contexts:

• By alteration or oxidation of iron-containing minerals.

• In banded iron formations (ancient sedimentary layers rich in iron).

• As a by-product in hydrothermal deposits.

The main producers are:

• Brazil

• Australia

• China

• India

• Russia

⚙️ Uses

1. Metallurgy : It is a major source of iron , used to make steel.

2. Pigments : Powdered hematite produces a red pigment (red ochre), used since prehistoric times (particularly in cave paintings).

3. Ornamentation : Polished, it is used in jewelry and lithotherapy .

4. Scientific applications : It has been detected on Mars, indicating the possible presence of water in the past.

🧘♀️ Symbolism and lithotherapy

In the field of lithotherapy (unconventional medicine):

• It is associated with anchoring and stability .

• It would help reduce stress , promote concentration , and strengthen self-confidence .

• It is also said to have protective properties against negative energies.
  

  🧲 Magnetism

  Pure hematite is not magnetic, but some forms (such as degenerate magnetite or magnetic hematite ) may exhibit weak magnetism.
