A beautiful, small iron-nickel meteorite.The majority of meteorites originate from asteroid belts located between Mars and Jupiter.On average, the distance to these belts ranges around 190 million kilometers. Their weight is immense: a solid sphere of this material with a diameter of just under 3 meters would weigh around 100 tons!It is estimated that this largely unaltered material is approximately 4.5 billion years old. None of the rocks on Earth are of comparable age.Following tips from indigenous people, Spanish colonialists discovered scattered fragments of an iron meteorite on a vast plain in Argentina in 1576. The meteorite was named after its discovery site, which the Spanish conquerors called “Campo del Cielo”—“Field of Heaven.” However, since their campaigns were primarily focused on looting gold or silver, the site was initially forgotten.Much later, researchers discovered that this iron was of meteoritic origin, and we now know that a large iron meteorite struck this area approximately 5,000 years ago.Locality: ArgentinaSize: approx. 1 cmPlease note: Iron meteorites contain a certain amount of nickel. People with nickel allergies should avoid direct skin contact or wear rubber gloves when handling them.Colors in product photos may differ from those of the original specimen for technical reasons.Our pictures are for reference only, you will receive a specimen of equivalent quality with your purchase.

Beautiful, small iron meteorite.Supplied in a collector's box.Locality: Sikhote-Alin Mts., RussiaSize: approx. 2 cmWeight: 7gSize of box: approx. 3.5 x 5.5 cmThis is a fragment of an iron meteorite which fell on 12 February 1947 over Eastern Siberia close to the Sikhote-Alin Mountains, in front of more than 240 eyewitnesses. In an air burst, thousands of fragments created over one hundred impact craters in the permafrost soil. The largest crater of 6 meters depth measures 26 meters in diameter, sound and light of the largest meteorite fall in recent times could be seen in 300km distance!In this meteorite event, fragments were severely warped and formed sharp edges, which is why they're referred to as "shrapnels".The Sikhote-Alin meteorite was made up of 93% iron and likely used to be an asteroid which got deflected from its original orbit. Before entering Earth's atmosphere, it's estimated to have weighed around 100 tons, 70 of which crashed onto Earth. A collective 30 tons have been found as scattered fragments of various sizes and weight.Note: Iron meteorites contain a certain amount of nickel. People with nickel allergies should avoid direct skin contact or wear rubber gloves when handling them.Colors in product photos may differ from those of the original specimen for technical reasons.Our pictures are for reference only, you will receive a specimen of equivalent quality with your purchase.
