Gibeon Meteorite

Nickel-Iron Meteorite (Octahedrite) · Meteoritic Material

Gibeon Meteorite

Crystal System

Cubic (Isometric) for kamacite and taenite phases

Mineral Group

Native Elements

Chemical Formula

Fe,Ni with trace amounts of Co, P, Ga, Ge, and Ir

Formation Process

Extraterrestrial crystallization from a molten planetary core asteroid, cooling over millions of years at a rate of a few degrees per million years

About This Crystal

This is a polished and etched cut section of a metallic iron meteorite displaying a distinct Widmanstätten pattern. The pattern consists of intersecting lamellae of kamacite and taenite, characteristic of medium octahedrites. The metallic luster shines with silvery-gray tones, showing linear grain structures and etched crystal boundaries.

Physical Characteristics

Metallic gray body color, dark grey to black streak due to metallic nature, no cleavage, hackly fracture, high specific gravity around 7.8 to 7.9, malleable to somewhat brittle depending on nickel content, highly magnetic.

Optical Properties

Opaque with a strong metallic luster. No refraction, birefringence, or traditional optical gemstone phenomena; instead, it exhibits anisotropic etching patterns (Widmanstätten figures) when treated with acid.

Hardness & Durability

Origin Region

Great Namaland, Namibia (Gibeon desert area), formed in the asteroid belt

Hardness & Durability

Mohs hardness around 4 to 4.5. Good toughness, but highly susceptible to oxidation (rusting) if exposed to moisture and humidity. Requires protective sealing for long-term preservation.

Care & Maintenance

Keep completely dry and store in a low-humidity environment with silica gel. Clean only with a dry cloth or specialized mineral oil/Renaissance wax to prevent oxidation. Avoid water, harsh chemicals, and ultrasonic cleaners.

Rarity & Value

Rare and highly collectible. Value is determined by weight, provenance, perfection and beauty of the Widmanstätten pattern, and the absence of terrestrial weathering. Prices range from moderate to high for certified Gibeon fragments.

Special Characteristics

Exhibits the iconic Widmanstätten pattern (or Thomson structures), which are unique nickel-iron crystal intergrowths that can only form in microgravity over millions of years of extremely slow cooling inside an asteroid core.

Lore & History

Discovered extensively in prehistoric times by the indigenous Nama people, who used the iron to craft tools and weapons. In modern metaphysical practices, meteorite is believed to facilitate spiritual grounding, transformation, and a connection to cosmic energy, though these remain traditional beliefs rather than scientific facts.
