112 g Pallasite meteorite slice showcasing Widmanstätten pattern, 4 bln years old

Rarity and Value
This 112-gram slice of a Pallasite meteorite represents one of the most exceptional and visually arresting classes of extraterrestrial material. Pallasites are among the rarest meteorites known, formed at the boundary between the metallic core and silicate mantle of differentiated asteroids. The prominent Widmanstätten pattern, revealed within the iron-nickel matrix after precise cutting and etching, enhances both its scientific importance and aesthetic power. Despite its moderate size, this specimen possesses remarkable scientific significance and is highly desirable for discerning collectors and educational displays.

Discovery and Significance
Formed approximately 4 billion years ago, this Pallasite originates from the earliest epoch of Solar System development. Such meteorites crystallized deep within protoplanetary bodies that were later fragmented by catastrophic collisions. As transitional material between core and mantle zones, Pallasites provide rare physical evidence of planetary differentiation — the same fundamental process that shaped Earth’s internal structure. Each slice serves as a preserved fragment of an ancient world that no longer exists.

Morphology and Preservation
Measuring 18 × 10.5 cm and weighing 112 grams, the slice displays a striking iron-nickel matrix intersected by crystalline structures, with the Widmanstätten pattern clearly visible across the polished surface. The natural geometric intergrowth of metallic phases reflects extremely slow cooling within a primordial asteroid core. Carefully cut and stabilized, the specimen maintains structural integrity while allowing detailed observation of its internal architecture, preserving both scientific clarity and visual refinement.

Human and Scientific Connection
As a museum-style artifact, this meteorite slice establishes a direct connection between human observation and deep cosmic time. It transforms abstract astrophysical processes into a tangible object formed billions of years before Earth reached its present state. The specimen bridges planetary science and human curiosity, preserving a fragment of primordial planetary history within a refined and contemplative display.
