Seymchan pallasite siderite meteorite (Russia) slice, beautifully etched on both faces to reveal a complex lattice-like Widmanstatten pattern. The full etched slice weighs 261.9 grams and measures approximately 137 mm x 86 mm x 4 mm. In fine condition. Accompanied by a certificate of authenticity signed by Geoff Notkin of Aerolite Meteorites Inc. and the TV show Meteorite Men. While Seymchan is officially classified as a pallasite meteorite (comprised of an iron and olivine mixture), this piece shows only iron and is thus described as a siderite specimen. This example features an especially appealing shape and etch pattern.
