    Iron, coarse octahedrite
    Maritime Territory, Siberia, Russia

    The current offering also originates from the largest meteorite shower since the dawn of civilization (see previous description) - and it's fortuitous it occurred in Siberia quite far from civilization. This specimen was ripped from a larger mass by the colossal force of having slammed into Earth's atmosphere at a cosmic velocity of ~14 miles a second. The rhombic shape is the result of a larger mass having been splintered along its crystalline planes in a low altitude explosion; (if it were an upper altitude explosion, the specimen would exhibit the thumbprints seen in the following lot). The reverse features the fluted exterior surface while the obverse has been cut and etched to reveal its internal structure: a coarse octahedral Widmanst├Ątten pattern - a crystalline matrix whose appearance is diagnostic in the identification of iron meteorites. This pattern forms as a result of there being few molecules in the vacuum of outer space to which a hot object can dissipate heat, so molten iron can remain warm in space for a million years or more - which is precisely what is required for the molecules of taenite and kamacite, two nickel-iron alloys, to orient into their crystalline habit. The cut surface also reveals Neumann bands, the result of an extraordinary collision in outer space that was more immense than its collision with Earth. A captivating example of a cataclysmic event frozen in time, from the most terrifying meteorite shower of modern times. 109 x 79 x 34 mm (4.25 x 3 x 1.25 inches) and 439.1 grams (1 pound).
