Seymchan is a well-known pallasite, discovered in 1967 in Siberia. Pallasites are formed at the interface between the core and mantle of asteroids and are among the most beautiful meteorites. Seymchan combines an iron-nickel matrix with olivine crystals in shades of gold and green. It is valued not only for its aesthetics, but also for the beautiful Widmanstätten patterns in the metal part. It is among the most sought-after pallasites on the market.
