    Iron Meteorite Ungrouped - IR-UNGR
    Sahara Desert / Algeria
    NWA 6932 is unlike any of the other iron meteorite offered in this sale. This complete slice - naturally shaped like the head of a bird - originates from an extremely exotic 32 kilogram meteorite found in the Sahara in 2008. In terms of its internal structure, there is no other meteorite that looks like NWA 6932 (see lots 49233, Seymchan and 49250). Moreover, in the words of Dr. John Wasson, the world's foremost expert in iron meteorites, "This meteorite has no close compositional relatives." As it does not fit into any of the established chemical groups, this meteorite has been classified as belonging to an esteemed meteorite classification: it is "ungrouped." In addition, this is one of the few plessitic iron meteorites (it contains plessite or fine grains of the chief iron alloys found in iron meteorites). Usually the plessite occurs in gaps between the bands which form a Widmanstatten pattern (see lot 49251) - but not in this rarest of birds. Featuring a single large troilite (iron sulfide) inclusion, as well as unique kamacitic spindles and crosses, this is the single most aesthetic complete slice from one of the more exotic iron meteorites on record. 227 x 114 x 5 mm (9 x 4.5 x 0.2 inches) and 684 grams (1.5 pounds).
