If “Iron, IAB-MG” means something to you, then this is your piece. The scientific classification of this Campo de Cielo meteorite fragment. Typical “crumbled” Iron-Nickel masses, 38 grams heavy and a strong metallic luster. The Campo del Cielo refers to a group of iron meteorites that are found in an area of the same name about 1000 km northwest of Buenos Aires, Argentina, between the provinces of Chaco and Santiago del Estero. Depending on the author of the study, the estimates of the fall of the meteorite varies from 4,000 to 6,000 years.
And I am sure you are hellbent to learn that “Campo del Cielo meteorites are a daily reminder of that philosophy, and will help clear the air of any and all negativity that may be surrounding you and affecting your daily decision making. By providing this impenetrable etheric shield, one will not only have inner peace, but also be able to listen to your instinctual desires.”(Quote from https://thecrystalcouncil.com/crystals/campo-del-cielo-meteorite). If that is not convincing enough to bid on that piece, what is???
