History & Origin of Hematite
Hematite has been used and admired for thousands of years. It was first discovered in ancient times and has been found in various archeological sites around the world. The name “hematite” comes from the Greek word “haimatites,” which means “blood-like,” referring to the red streak it produces when rubbed on a rough surface.
Throughout history, hematite has been valued for its iron content, which made it an essential resource for producing tools, weapons, and ornamentation. Different cultures have attributed various meanings to hematite, such as grounding, protection, and strength. In ancient Egypt, for example, hematite was used as a pigment for pottery and cosmetics, while the Romans believed it to have healing properties.
Hematite Identification & Physical Properties
To help you identify hematite, here’s a table outlining its most notable physical properties:
| Property | Description |
|---|---|
| Color | Steel-gray to black, with a reddish-brown streak |
| Luster | Metallic to submetallic |
| Hardness | 5.5 – 6.5 on the Mohs scale |
| Transparency | Opaque |
| Crystal System | Trigonal |
| Fracture | Uneven to subconchoidal |
| Cleavage | None |
Hematite Colors
Hematite is typically steel-gray to black in color, with a metallic or submetallic luster. One of its distinguishing characteristics is its reddish-brown streak, which becomes evident when the mineral is rubbed on a rough surface or powdered.
Hematite Hardness
On the Mohs scale of mineral hardness, hematite ranges from 5.5 to 6.5, making it a relatively hard mineral. This hardness contributes to its durability and resistance to scratching, making it suitable for various applications and uses.
Hematite Types
Hematite occurs in various forms, each with its unique characteristics. Some of the most common types of hematite include:
Specular Hematite
Specular hematite, also known as specularite, is characterized by its metallic luster and shiny, reflective surfaces. It often forms in thin layers or plates, giving it a mirror-like appearance.
Botryoidal Hematite
Botryoidal hematite has a rounded, grape-like or kidney-shaped surface, formed by the accumulation of tiny hematite crystals. This type of hematite is often found in the cavities of rock formations and can have a glossy or matte finish.
Oolitic Hematite
Oolitic hematite consists of small, rounded grains or ooids, which are cemented together to form a solid mass. The ooids are typically composed of concentric layers of hematite, giving the mineral a unique texture and appearance.
Hematite Uses
Hematite has a wide range of uses, including:
- As a major source of iron for the production of steel and other iron-based products
- In the manufacturing of pigments for paints, inks, and ceramics
- As a polishing compound for metals, glass, and jewelry
- In magnetic materials and devices due to its natural magnetic properties
- As an ornamental stone for jewelry, carvings,and decorative items
How Much Is Hematite Worth?
The value of hematite can vary greatly depending on factors such as size, quality, and form. Specimens used for decorative purposes or as collector’s items can range from a few dollars to a couple of hundred dollars. Higher-quality specimens, such as those with a unique crystal structure or aesthetic appeal, can be worth more. It’s essential to keep in mind that the market for hematite is constantly changing, so prices can fluctuate over time.
