This 7.05 gram pallasite meteorite was discovered in Russia in 1967. It is officially classified as Seymchan by the International Society for Meteoritics and Planetary Sciences. This slice has been cleaned, polished, and coated in a protective epoxy. The olivine crystals are transparent in places, allowing light to illuminate through the meteorite. 

The Seymchan meteorite is a spectacular pallasite discovered in the Magadan region of eastern Russia in the late 1960s. Pallasites are among the rarest meteorites and are thought to originate from the boundary between the metallic core and rocky mantle of a differentiated asteroid. Seymchan is especially intriguing because it spans categories: some specimens are nearly pure nickel-iron, while others contain translucent green olivine crystals embedded in metal, offering a natural cross-section of planetary formation processes. When cut and etched, its metal reveals striking Widmanstätten patterns -- interlocking crystal structures that only form during extremely slow cooling over millions of years in space.

Unique Features of This Meteorite

Stony-iron meteorites are a rare and visually striking type of meteorite composed of roughly equal parts silicate minerals and metallic iron-nickel. They offer a unique glimpse into the boundary between the metal core and rocky mantle of ancient planetary bodies. The two main types—pallasites and mesosiderites—are prized by collectors and scientists for their beauty and scientific value.
