This part-slice of solid Hoba, with a mass of 25.3 g and of good provenance, has been residing in my collection for 21 years now. There is a good description of this Ataxite in Vagn Buchwald´s Handbook of Iron Meteorites, Vol. 2, pages 647-650, where you will also find a photo of this somewhat cloudy structure seen on polished faces, which are typical for this iron, and can also be seen in this picture here. Very hard to obtain (as solid material) nowadays, except for tiny shale crumbs maybe, as no more specimens have been cut from this strictly protected famous meteorite for many decades. This is from a very early cut in the pre-protection times, and one of the prior owners was a museum in the heart of Europe. |

Fabulous, virginal slice, with sharply defined patchwork from the mega-meteorite, Alex, which is the largest naturally occurring mass of steel (estimated up to 66 MT) on the face of the Earth, though not from Earth at all! For comparison & fo fun: with steel, the original Chicago Ferris Wheel weighed 943 MT, The High Roller ferris wheel currently in Las Vegas 4,500 MT, and the Eiffel Tower, 10,100 MT, and the Burj Khalifa around 35,000 MT in its structure. Thank you for the great photos and welcome back Alex!!! |

@Matthias and Bernd: thank you for the comments, my dear meteorite friends. Yes, indeed, this is a rarity. Just an addition: this slice is prepared (polished) only on the side shown, the backside still has saw marks, so that it doesn*t show the texture as clearly as on the pic shown here. The outside (irregular rim) mimics some sort of crusty freshness, but in fact it has been exposed to the SW-African climate for tenthousands of years, so it has somehow altered and decayed, and is not really "fresh" in the sense of the word. I do not know who prepared that, but I have info on three prior owners, all of them very reputable, including one institute/museum, but please understand for privacy reasons that I will not reveal names here. |

Beautiful and characteristic oriented sheen. Thanks for sharing! |

A rare piece indeed from this meteoritical record-holder as a single iron mass. Ad not at least: one side with original surface. Not much better to get from Hoba, Alex. |
