A Mixed Pallasite & Mesodiderite Meteorite. An iron-nickel meteorite named Seymchan was found in the Magadan district of far east Russia in 1967. A 312 kg meteorite was found and when it was cut and polished it looked to be just an iron-nickel meteorite. But in 2004 several more Seymchan meteorites were found in the same location; when they they were examined closer, some unique properties were discovered. They were not just an iron-nicket meteorite but small parts of their internal structure contained crystals of olivine, making them a much rarer Pallasite or stony-iron meteorite. Pallasites are known as gem stones from space because of the beautiful yellow and green olivine crystals, also known as Peridot. The story does not end there. A very small percentage of Seymchan meteorites also contain much silicate, which also makes them a Mesosiderite meteorite, which could only have been formed from a collision between two differentiated asteroids. This beautiful and impressive full section of Seymchan is 21x10" and weighs an unbelievables 57.8 pounds and has been etched on both sides to show the widmanstatten pattern that is distinctive of iron-nickel meteorites. This large section has it all: areas of olivine crystals around the edge, large graphite and silicate inclusions, and the original fusion crust around the edges. It is a once-in-a-lifetime opportunity to purchase such a large, important meteorite section that would be a highlight specimen in any museum. Pallasites are normally sold by the gram, not by the pound.
