This nickel iron meteorite fell on Feb. 12, 1947 in the Sikhote-alin Mountains of Eastern Siberia, Russia. It is the largest observed meteorite fall in history, with over 23000 kg raining down on the earth in the form of iron shrapnel and the more rare individual fallen meteorites such as this one. It is covered in regmaglypts, the indentations that give the piece contours. I put this piece away, back when this meteorite was readily available on the market. A couple years ago, the Russian government has made it difficult to export, and diggers I knew said there was almost nothing left to find. 

This fine example weighs 52.80 grams. It's in fine condition.
