This thin, square-shaped tablet of Iron-nickel comes from a siderolite meteorite, a variety of metallic meteorite that has stony inclusions trapped within. A small spherule of a dark material that is composed mainly of carbon is visible on one of the specimen's main faces. The piece has been cut on all but one side, where some of the natural outer surface of the meteorite is still visible. The cut faces have been polished and acid-etched, bringing out the Widmanstatten figures that are made up of crystallized polymorphs of the nickel-iron compound, called kamacite and taenite that intersect each other at certain angles. It has the standard gray color and metallic luster of iron-nickel. Metallic meteorites represent about 6% of all stellar material that reaches Earth.
