Meteorite cut, polished and treated with a nitric acid solution so that the Widmanstätten structures can be seen. 
The Widmanstätten structures They are the result of the intergrowth of bands of taenite y camacita, two alloys of iron y nickel, produced by very slow cooling (of the order of 100 ºC to 10,000 ºC per million years), over periods of up to 10 million years. This structure cannot be reproduced in the laboratory, so its presence constitutes unequivocal proof of the authenticity of a meteorite. They are present in certain metallic meteorites y lithosiderites. 
The box is included in the price.
