Silicated Iron, IAB

    The meteorite from which this large end piece originated was recently found by nomadic Berbers in southern Algeria. It does not as yet have a name - a situation to be soon remedied by the Meteoritical Society's Nomenclature Committee. On December 3rd, 2008 UCLA scientists announced that only one other meteorite exists whose composition is identical the meteorite now offered - and there are only seven pounds of that Australian meteorite.

    Featuring the signature appearance of the most resplendent silicated iron meteorites, this end piece showcases large, dark silicate inclusions suspended throughout a crystalline metallic matrix; an intergrowth of alloys whose appearance is diagnostic in the identification of a silicated iron meteorite.

    This is the largest end piece from the second largest mass associated with this meteorite shower - a very spare event by iron meteorite standards. The total known weight of the entire shower with which this meteorite is associated is less than 200 kilograms - most iron meteorite showers include one meteorite that weighs more.

    The external surface of the specimen now offered has a dull platinum patina - a most atypical finish that is the result of natural sandblasting in the Algerian desert over a period of at least hundreds of years. The external surface also features swatches of glazed fusion crust, the result of burning through the atmosphere during its descent to Earth. Mounted on a custom armature, and with a Macovich Collection provenance - the finest collection of aesthetic iron meteorites in the world - his is a rarely available large end piece of an exotic meteorite. 4,285 grams (9.5 pounds) and 199 x 133 x 74 mm (7.75 x 5 x 3 inches).

    We had a wonderful time in New York during the October 2013 Historical Manuscripts auction that featured my mother’s papers collected during her tenure as Martin Luther King, Jr.’s secretary. In fact, the entire experience from beginning to end has been a pleasure.
