Muonionalusta Meteorite Slice with Troilite Inclusion on Steel Spinner Stand

A Muonionalusta Iron Meteorite Slice — One Million Years on Earth, 4.5 Billion Years Old

The Muonionalusta is not merely a rare meteorite — it is the oldest known meteorite to have rested on Earth's surface, having fallen in what is now northern Sweden approximately one million years ago during the Pleistocene epoch. Sliced and etched to reveal its extraordinary internal structure, this specimen displays the finest and most geometrically precise Widmanstätten pattern of any known iron meteorite class — a crystalline architecture that formed over millions of years of slow cooling in the asteroid parent body and cannot be replicated by any terrestrial process. A troilite inclusion — a nodule of iron sulfide (FeS) that crystallized within the meteorite's parent body before it ever reached Earth — adds a second distinct mineral phase visible on the polished face. Mounted on a steel spinner stand, this 5.8 lb slice is a museum-caliber acquisition.

Scientific & Mineralogical Profile

• Classification: Iron meteorite — IVA structural class; one of the most nickel-rich and fine-structured of all iron meteorite groups, with kamacite and taenite as the dominant mineral phases
• Widmanstätten Pattern: The IVA class produces the finest, most geometrically regular Widmanstätten pattern of any iron meteorite group — interlocking crystalline bands of kamacite (α-iron) and taenite (γ-iron) that formed during millions of years of slow cooling at approximately 1°C per million years in the asteroid parent body; visible to the naked eye on the etched face and physically impossible to replicate artificially
• Troilite Inclusion: A nodule of troilite (FeS — iron monosulfide) embedded within the iron-nickel matrix; troilite is one of the oldest minerals in the solar system, crystallizing in the parent body during its earliest formation phase; its presence within the meteorite slice is a direct window into the primordial chemistry of the early solar system
• Composition: Approximately 91% iron, 8–9% nickel, with trace cobalt, phosphorus (schreibersite), and carbon (cohenite) — plus the troilite (FeS) inclusion as a distinct mineral phase
• Origin: Muonionalusta strewn field, Norrbotten County, northern Sweden — first discovered in 1906; additional masses recovered through the 20th century across the Swedish-Finnish border region
• Terrestrial Age: ~1 million years — the longest confirmed terrestrial residence of any known meteorite; survived multiple glacial cycles of the Pleistocene ice ages
• Parent Body Age: ~4.5 billion years — formed during the earliest accretion of the solar system
• Stand: Steel spinner stand — allows 360° rotation for full access to both the etched Widmanstätten face and the natural exterior surface
• Dimensions: 14.5″ H × 5.5″ W × .25″ D (stand included)
• Weight: 5.8 lbs (~2,630 g)

Historical & Cultural Significance

The Muonionalusta meteorite was first discovered near the Muonio River in Norrbotten, Sweden in 1906, though the strewn field was not fully recognized until subsequent recoveries in the mid-20th century. Its extraordinary terrestrial age — confirmed by cosmogenic nuclide dating — means this meteorite lay buried in the Swedish subarctic through the entire Pleistocene epoch, surviving the advance and retreat of multiple continental ice sheets. The Widmanstätten pattern it displays was first described scientifically by Count Alois von Beckh Widmanstätten in Vienna in 1808 — a discovery that fundamentally changed humanity's understanding of the extraterrestrial origin of iron meteorites. Muonionalusta slices are among the most prized meteorite specimens in the world for their aesthetic perfection and scientific significance, held in major natural history museum collections across Europe and North America.

Metaphysical & Energetic Properties

• Oldest Terrestrial Meteorite: Having rested on Earth for one million years, the Muonionalusta carries a depth of earth-integration unmatched by any other meteorite class — a bridge between cosmic origin and deep terrestrial presence
• Iron-Nickel Matrix: Iron grounds and protects — associated with the root chakra, physical strength, willpower, and the anchoring of spiritual energy; nickel adds resilience, adaptability, and the capacity to hold form under pressure
• Troilite Inclusion: As one of the oldest minerals in the solar system, troilite carries the energetic signature of primordial creation — associated with the first moments of solar system formation and the deepest layers of cosmic memory
• Widmanstätten Geometry: The precise geometric crystalline pattern is associated in sacred geometry traditions with divine order, the mathematics of the cosmos, and the intelligence embedded in natural structure
• Root & Crown Bridge: Like all iron meteorites, the Muonionalusta simultaneously grounds (iron/root chakra) and expands (cosmic origin/crown chakra) — but its million-year terrestrial age makes the grounding dimension exceptionally deep and stable

Display & Care

• Display: Arrives on its steel spinner stand — 360° rotation allows full viewing of the etched Widmanstätten face, the troilite inclusion, and the natural exterior; place on a stable surface capable of supporting the specimen
• Rust Prevention: Iron meteorites oxidize in humid environments; store in low humidity and apply a thin annual coat of Renaissance Wax or archival-grade clear lacquer to the etched face and exterior
• Cleaning: Wipe with a soft, dry cloth only; avoid all water contact; never use acidic, alkaline, or chemical cleaners — acids will dissolve the etched Widmanstätten pattern
• Handling: Use clean, dry hands or cotton gloves — skin oils accelerate surface oxidation and can stain the etched face over time
• Authenticity: A genuine Muonionalusta IVA iron meteorite slice from the documented Norrbotten strewn field — one of the most scientifically verified and aesthetically prized meteorite localities in the world
