Unique Meteorite Egg-form Carving

Coarse Octahedrite
Gran Chaco, Argentina

The famous iron-nickel meteorite, Campo del Cielo, fell to Earth over 4,000 years ago in the mountainous region of Gran Chaco, Argentina, 500 miles north-northwest of Buenos Aries, in one of the largest and undoubtedly most dramatic falls of the last 10,000 years. Meteorites from this fall were scattered over hundreds of square miles of inaccessible terrain. The present egg-shaped specimen has been polished and etched to show its Widmanstatten pattern, which results from two alloys of nickel in the meteorite etching at different rates. No iron-nickel rocks on Earth exhibit this pattern, which occurs when the extraterrestrial metals cool at the very slow rate of several degrees per million years. Also seen in this specimen is an interesting troilite inclusion. Offered with a display stand. Measuring 2 ¼ x 1 1/5in; Weight 500 grams
