This 251.01g slice of Seymchan comes from one of the metal-rich parts of the meteorite. Its etched face is almost entirely iron-nickel, with a bold Widmanstätten pattern of broad kamacite bands crossing in large, bright panels. The irregular, lobed outline is rimmed with brown weathered crust along the natural edge, and the size of the slice lets the full sweep of the pattern be seen at once.

Seymchan is a well-known Pallasite from the Magadan region, first found in 1967 in a stream bed near the settlement of Seymchan. It was originally regarded as an Iron meteorite, but later finds revealed olivine-bearing material, leading to its classification as a Main Group Pallasite. Seymchan is notable for its variable structure, with some specimens showing classic Pallasite olivine in metal, while others are almost entirely metallic.

Prepared Seymchan specimens can vary widely in appearance. Olivine-rich pieces show yellow to green crystals set within iron-nickel metal, while metal-rich pieces can display strong Widmanstätten patterns when cut, polished and etched. This natural variation makes Seymchan especially interesting, as it can appeal to both Pallasite collectors and those drawn to patterned Iron meteorites. Its relative stability also makes it a popular choice for display and jewellery.

For collectors, Seymchan offers a recognised and visually versatile Stony-Iron meteorite with strong scientific and aesthetic appeal. Its long documented history, Main Group Pallasite classification and range of specimen types make it suitable for both specialist collections and striking display pieces. Each specimen represents asteroid material that formed over 4.5 billion years ago, preserving both metallic and silicate phases from the early Solar System.
