This thin, rectangular slab was cut from a metallic meteorite with stony inclusions called a siderolite. All but one face on the piece has been cut; the one that is uncut shows a small portion of the meteorite's outer surface, which is rather dark, uneven, and rusty. The other faces are flat; they have been polished and etched with an acid so as to bring out designs on the faces caused by the alignment of two polymorphs of the iron-nickel compound. These designs are called Widmanstatten figures Along with these designs are a tiny, dark, oval spherules of a compound made up mostly of carbon. A siderolite meteorite is a variety of metallic meteorite that contains stony inclusions- this type of meteorite represents a small fraction of the total stellar material that actually makes it to the Earth's surface.
