Exceptional Seymchan pallasite sphere measuring 59 mm in diameter and weighing 562 g, meticulously shaped and polished to a true mirror finish. The sphere reveals a spectacular distribution of translucent olivines embedded within the iron-nickel matrix, producing remarkable golden and amber reflections under light. Creating a perfectly balanced sphere from a pallasite requires extremely precise cutting and polishing due to the contrasting hardness between metal and silicate crystals. The final mirror-polished surface enhances both the Widmanstätten structures and the internal translucency of the olivines, transforming this meteorite into both a scientific specimen and a sculptural display piece. A rare and highly aesthetic Seymchan pallasite sphere combining technical preparation, natural extraterrestrial beauty, and strong collector appeal.
The sphere format significantly increases value compared to standard slices because of:
This remarkable Seymchan pallasite sphere measures 59 mm in diameter and weighs 562 g. Entirely shaped and polished by hand, the specimen combines the complex internal structure of a pallasite with the visual perfection of a true geometric sphere.
The preparation of a meteorite sphere of this quality requires extremely precise work. Pallasites are particularly difficult to shape because the metallic matrix and the olivine crystals react differently during cutting and polishing. Achieving a perfectly spherical form while preserving both structural balance and surface integrity demands considerable expertise and time.
The surface has been polished to a genuine mirror finish, creating intense reflections within the metallic matrix while simultaneously enhancing the translucency of the olivines. Under direct light, the crystals display luminous green, golden, amber, and honey-colored tones characteristic of high-quality Seymchan pallasite material.
Unlike flat slices, a sphere offers a continuously changing visual experience. As the specimen rotates, the internal architecture evolves from every angle, revealing different olivine concentrations, metallic structures, and contrasting textures across the entire surface.
The spherical preparation transforms the meteorite into both a scientific specimen and a sculptural object. The continuous curved surface enhances the natural contrast between reflective iron-nickel metal and translucent extraterrestrial olivines.
The polished metallic matrix acts almost like liquid metal, while the embedded crystals appear suspended within it. This interaction between transparency and reflection gives the sphere exceptional visual depth.
The Seymchan meteorite was discovered in the Magadan region of eastern Siberia and is one of the most important transitional pallasites known.
Unlike many classical pallasites, Seymchan contains both metallic sections and olivine-rich zones, making every specimen unique in structure and appearance.
Its etched and polished surfaces reveal Widmanstätten structures formed during extremely slow cooling inside the core of a differentiated asteroid billions of years ago.
Producing a mirror-polished finish on a pallasite is technically demanding. The polishing process must preserve the integrity of both the metal and the olivine crystals while avoiding differential erosion between materials of different hardness.
The result is a highly reflective surface capable of revealing fine structural details while amplifying the natural transparency of the olivines.
Meteorite spheres of this quality are considerably rarer than conventional slices due to the complexity of preparation and the amount of material required.
This specimen is particularly suited for:
Its combination of perfect geometry, mirror polish, translucent olivines, and extraterrestrial origin makes it both a natural object and a refined display sculpture.
